Question

The nurse anticipates that the malnourished postoperative 70-year-old patient will receive an Intravenous (IV) Infusion of 5% dextrose in 0.45% saline, because it is:

Answer 1

Correct Answers:

hypotonic

Rationale :

🔷 5% dextrose in 0.45% saline (D5 ½ NS) acts as a hypotonic solution after the dextrose is metabolized by the body.

🔷 Hypotonic fluids help move water from the bloodstream into the cells, promoting cellular hydration.

🔷 This solution is often used in postoperative or elderly patients who need hydration with a small calorie source.

🔷 The dextrose provides temporary energy while the saline helps replace fluid losses.

🔷 Careful monitoring is necessary because excessive hypotonic fluids can increase the risk of fluid overload or cellular swelling in older adults.

Incorrect Answers

❌ Isotonic

🔷 Isotonic solutions have the same osmotic pressure as plasma and do not cause fluid shifts between compartments.

🔷 Examples of isotonic fluids include 0.9% normal saline and Lactated Ringer’s, not D5 ½ NS.

❌Hypertonic

🔷 Hypertonic solutions pull water out of the cells into the bloodstream.

🔷 D5 ½ NS does not primarily function as a hypertonic fluid once the dextrose is metabolized.

❌ Total parenteral nutrition

🔷 Total parenteral nutrition (TPN) contains concentrated nutrients such as amino acids, lipids, vitamins, and glucose.

🔷 D5 ½ NS only provides fluids and limited calories, not complete nutritional support.

Answer 2

Correct Answers:

presence of occult blood.

Rationale :

🟢 Black, tarry, sticky stool is known as melena, which commonly indicates digested blood in the gastrointestinal tract.

🟢 Bleeding usually originates from the upper GI tract, such as the stomach or duodenum.

🟢 Blood becomes dark as it passes through digestive enzymes and intestinal bacteria.

🟢 Conditions like gastric ulcers, esophageal varices, or gastritis may cause this finding.

🟢 This assessment finding requires prompt evaluation because GI bleeding can become life-threatening.

Incorrect Answers

❌ Blockage of the bile duct

🟢 Bile duct obstruction usually produces clay-colored or pale stools, not black stools.

🟢 Lack of bile pigments prevents the stool from having its normal brown color.

❌ Blockage of the pancreatic duct

🟢 Pancreatic duct obstruction may interfere with fat digestion and lead to fatty stools.

🟢 It does not typically cause black, tarry stools.

❌Recent excessive intake of milk products

🟢 Excess milk intake may contribute to constipation or lighter-colored stool.

🟢 It does not usually produce melena or sticky black stool.

Answer 3

Correct Answers:

is bacterial and should respond to treatment with antibiotics.

Rationale :

🟣 Pneumococcal pneumonia is caused by Streptococcus pneumoniae, which is a bacterium.

🟣 Bacterial infections generally respond well to prescribed antibiotic therapy when treated early.

🟣 Common symptoms include fever, productive cough, chest pain, and shortness of breath.

🟣 Older adults and immunocompromised patients are at greater risk for complications.

🟣 Vaccination against pneumococcus helps reduce the incidence and severity of infection.

Incorrect Answers

❌ Is viral and will not respond to antibiotics

🟣 Viral pneumonia is caused by viruses such as influenza or RSV, not pneumococcus.

🟣 Antibiotics are specifically useful against bacterial organisms, including Streptococcus pneumoniae.

❌ Is fungal and is caused by alteration of the normal flora of the lung

🟣 Fungal pneumonia is usually associated with organisms like Histoplasma or Candida.

🟣 Pneumococcal pneumonia is not caused by fungal overgrowth.

❌ Is resultant from a resistant organism and extreme caution must be taken

🟣 Although antibiotic resistance can occur, pneumococcal pneumonia is not automatically classified as resistant.

🟣 Standard precautions and prescribed antibiotics are commonly effective in treatment.

Answer 4

Correct Answers:

frothy and foul smelling.

Rationale :

🟠 Steatorrhea means the stool contains excess fat due to poor fat digestion or poor fat absorption.

🟠 The stool is commonly bulky, greasy, frothy, pale, and foul smelling because undigested fat remains in the feces.

🟠 This may occur with pancreatic disease, bile flow problems, celiac disease, or other malabsorption disorders.

🟠 The patient may also have weight loss, abdominal discomfort, and deficiencies of fat-soluble vitamins A, D, E, and K.

🟠 Recognizing steatorrhea is important because it points to an underlying digestive or absorption problem that needs follow-up.

Incorrect Answers

❌ Hard and clay colored

🟠 Hard stool is usually linked with constipation, dehydration, or reduced bowel motility.

🟠 Clay-colored stool suggests reduced bile pigment in the stool, not excess fat.

❌ Very liquid and streaked with blood

🟠 Liquid stool with blood suggests diarrhea with intestinal irritation, infection, or inflammatory bowel disease.

🟠 Steatorrhea is mainly fatty and greasy, not bloody.

❌ Soft and filled with mucus

🟠 Mucus in stool may occur with bowel inflammation, infection, or irritable bowel conditions.

🟠 Steatorrhea is identified by fat malabsorption, not mucus production.

Answer 5

Correct Answers:

mentally review the procedure.

Rationale :

🔴 The nurse should first mentally review the procedure to organize the correct sequence of steps before performing care.

🔴 This helps promote patient safety by reducing the risk of missed steps, contamination, or procedural errors.

🔴 Mental review also helps the nurse identify needed supplies and prepare the environment before approaching the patient.

🔴 It supports confidence and efficiency, especially when the procedure requires sterile technique or careful timing.

🔴 A nurse who is unsure of the procedure should then consult policy, seek guidance, or review the agency procedure manual before proceeding.

Incorrect Answers

❌ Question the rationale for the procedure

🔴 Understanding the rationale is important because nurses must know why a procedure is being done.

🔴 However, the initial action before implementation is to mentally organize the procedure so it can be performed safely.

❌ Perform a physical assessment of the patient

🔴 A physical assessment may be needed before many procedures to determine whether the patient is stable and ready.

🔴 It is not the best initial step when the question asks what the nurse should do first before implementing the procedure.

❌ Check the agency manual for the procedure

🔴 The agency manual should be checked when the nurse is unfamiliar with the procedure or needs clarification about policy.

🔴 It is not always the first action if the nurse already knows the skill and simply needs to prepare for safe performance.

Answer 6

Correct Answers:

hypoxemia

Rationale :

🔵 Hypoxemia refers to a decreased amount of oxygen in the blood, especially in the arterial blood.

🔵 It may result from respiratory disorders such as pneumonia, COPD, pulmonary edema, or impaired gas exchange.

🔵 Common signs include low oxygen saturation, cyanosis, restlessness, tachycardia, and confusion.

🔵 Arterial blood gas analysis and pulse oximetry are commonly used to assess oxygen levels in the blood.

🔵 Severe hypoxemia can progress to tissue oxygen deprivation and organ dysfunction if not corrected promptly.

Incorrect Answers

❌ Hypoxia

🔵 Hypoxia refers to a decreased oxygen supply at the tissue or cellular level, not specifically in the blood.

🔵 A patient can have hypoxemia that later leads to hypoxia if tissues do not receive enough oxygen.

❌ Hypercapnia

🔵 Hypercapnia means there is an increased level of carbon dioxide (CO₂) in the blood.

🔵 It commonly occurs with hypoventilation or respiratory failure, not low blood oxygen alone.

❌ Dyspnea

🔵 Dyspnea describes the subjective feeling of difficulty breathing or shortness of breath.

🔵 It is a symptom experienced by the patient rather than a blood oxygen abnormality itself.

Answer 7

Correct Answers:

"Tell me about any religious practices you observe that we need to incorporate into your care."

Rationale :

🟣 This question is the most open-ended, respectful, and culturally sensitive because it allows the patient to explain personal beliefs and practices freely.

🟣 It avoids assumptions about how strictly the patient follows religious customs or which practices are important to them.

🟣 Open-ended communication promotes individualized nursing care and strengthens the therapeutic relationship.

🟣 Cultural sensitivity helps nurses provide care that respects the patient’s values, traditions, and spiritual needs.

🟣 Patients from the same religious group may practice their beliefs differently, so individualized assessment is essential.

Incorrect Answers

❌ Do you follow any dietary restrictions, or will you eat hospital food as it is prepared here?

🟣 Dietary practices are important, but this question focuses only on food and not the patient’s overall religious needs.

🟣 It may overlook other spiritual practices such as prayer, rituals, or Sabbath observance.

❌ Are there any medications or treatments your religion does not allow in your medical treatment?

🟣 Some religions may have treatment restrictions, but this question is too narrow in scope.

🟣 It does not fully assess the patient’s broader cultural and spiritual preferences.

❌ Would you like me to notify your rabbi so that he can make visits to you during your stay?

🟣 This question assumes the patient wants clergy involvement, which may not always be desired.

🟣 Culturally sensitive care begins with assessing the patient’s wishes rather than making assumptions.

Answer 8

Correct Answers:

sign out the drug on a narcotic control inventory sheet.

Rationale :

🟢 Schedule II medications are controlled substances with a high potential for abuse and dependence.

🟢 Nurses must follow strict legal and institutional guidelines when administering these medications.

🟢 Signing the medication out on a narcotic control inventory sheet ensures accountability and accurate tracking.

🟢 Proper documentation helps prevent medication diversion, misuse, and administration errors.

🟢 Examples of Schedule II drugs include morphine, fentanyl, oxycodone, and hydromorphone.

Incorrect Answers

❌ Leave the medication in a cup at the bedside

🟢 Controlled medications should never be left unattended at the bedside because of safety and legal concerns.

🟢 The nurse must verify that the patient actually takes the medication as prescribed.

❌ Ask another licensed nurse to check the dose

🟢 Double-checking may be required for some high-alert medications, but it is not the primary legal responsibility specific to Schedule II drugs.

🟢 The key responsibility is accurate control, documentation, and inventory management.

❌ Tell the patient to drink extra water with the pill

🟢 Some oral medications are taken with water to aid swallowing and absorption.

🟢 This instruction is unrelated to the special handling requirements of Schedule II controlled substances.

Answer 9

Correct Answers:

“international normalized ratio (INR)."

Rationale :

🟡 The INR is the primary blood test used to monitor patients taking warfarin (Coumadin) therapy.

🟡 INR measures how long it takes the blood to clot and helps determine whether the medication dose is safe and effective.

🟡 If the INR is too high, the patient is at increased risk for bleeding; if too low, the patient is at risk for blood clots.

🟡 Regular monitoring is essential because many foods, medications, and illnesses can affect warfarin activity.

🟡 Patients taking Coumadin are also taught to watch for signs of bleeding such as bruising, bloody stools, or bleeding gums.

Incorrect Answers

❌ Complete blood count (CBC)

🟡 A CBC measures components of the blood such as red blood cells, white blood cells, hemoglobin, and platelets.

🟡 Although it may help assess for anemia or infection, it does not specifically monitor the therapeutic effect of warfarin.

❌ Activated partial thromboplastin time (APTT)

🟡 APTT is mainly used to monitor heparin therapy, not Coumadin therapy.

🟡 Heparin affects the intrinsic clotting pathway, whereas warfarin is monitored with PT/INR values.

❌ Erythrocyte sedimentation rate (ESR)

🟡 ESR is a nonspecific test used to detect inflammation in the body.

🟡 It is commonly elevated in infections, autoimmune disorders, or inflammatory conditions, not for anticoagulant monitoring.

Answer 10

Correct Answers:

hypostatic pneumonia.

Rationale :

🔴 Immobilized patients are at high risk for hypostatic pneumonia because prolonged inactivity allows secretions to pool in the lungs.

🔴 Frequent deep breathing exercises help expand the lungs and improve ventilation.

🔴 Deep breathing also promotes coughing and movement of secretions, reducing bacterial growth in the respiratory tract.

🔴 Older adults and bedridden patients are especially vulnerable because of decreased lung expansion and weakened cough reflexes.

🔴 Nurses commonly encourage deep breathing, coughing, repositioning, and incentive spirometry to prevent respiratory complications.

Incorrect Answers

❌ Low oxygen saturation

🔴 Deep breathing may improve oxygen levels, but the primary purpose in immobilized patients is prevention of pulmonary complications.

🔴 Low oxygen saturation is a symptom or finding rather than the specific complication targeted in this question.

❌ Atelectasis

🔴 Atelectasis refers to collapse of alveoli due to shallow breathing or mucus obstruction.

🔴 Although deep breathing helps prevent atelectasis, prolonged immobility is more directly associated with hypostatic pneumonia in this context.

❌ Respiratory alkalosis

🔴 Respiratory alkalosis occurs when excessive carbon dioxide is lost due to rapid breathing or hyperventilation.

🔴 Deep breathing exercises do not primarily aim to prevent this acid-base imbalance.
