Question

A nurse is assessing a client who is experiencing respiratory acidosis. Which of the following manifestations should the nurse expect to observe?

Answer 1

Correct Answers:

Confusion

Rationale :

♠️ Respiratory acidosis occurs when inadequate ventilation causes retention of carbon dioxide (CO₂).

♠️ Increased PaCO₂ causes the blood pH to decrease below 7.35, producing acidemia.

♠️ Excess CO₂ readily crosses the blood-brain barrier and affects central nervous system function.

♠️ Neurologic manifestations can include headache, confusion, decreased level of consciousness, and drowsiness.

♠️ As respiratory acidosis becomes more severe, the client can develop increasing CNS depression.

♠️ The nurse should closely assess mental status, respiratory pattern, oxygenation, and ABG values.

♠️ Severe CO₂ retention can progress to CO₂ narcosis, respiratory failure, and coma if ventilation is not improved.

♠️ Confusion is therefore an expected manifestation of respiratory acidosis caused by the neurologic effects of hypercapnia.

Answer 2

Correct Answers:

Respiratory alkalosis due to hyperventilation

Rationale :

🌸 The client's pH is 7.48, which is above the normal range of 7.35–7.45, indicating alkalemia.

🌸 The PaCO₂ is 30 mm Hg, which is below the normal range of 35–45 mm Hg, indicating excessive carbon dioxide elimination.

🌸 Because CO₂ acts as an acid, losing excessive CO₂ causes the blood pH to increase.

🌸 This pattern occurs with hyperventilation, when ventilation exceeds the body's metabolic requirement for carbon dioxide removal.

🌸 The HCO₃⁻ is 24 mEq/L, which remains within the normal range of approximately 22–26 mEq/L.

🌸 A normal bicarbonate level suggests that significant renal compensation has not yet occurred, supporting an acute or uncompensated respiratory process.

🌸 Common causes of respiratory alkalosis include anxiety, pain, fever, hypoxemia, pulmonary embolism, and excessive mechanical ventilation.

🌸 The ABG pattern of ↑ pH + ↓ PaCO₂ + normal HCO₃⁻ therefore identifies uncompensated respiratory alkalosis caused by hyperventilation.

Answer 3

Correct Answers:

Neuropathic pain

Rationale :

♦️ Phantom limb pain is pain perceived in a limb or body part that has been amputated.

♦️ It results from abnormal activity within the peripheral nerves, spinal cord, and brain, rather than from ongoing tissue injury in the missing limb.

♦️ Clients may describe the sensation as burning, shooting, tingling, cramping, or electric-like pain.

♦️ These qualities are characteristic of neuropathic pain, which arises from injury or dysfunction within the nervous system.

♦️ The brain can continue to interpret signals as if they are coming from the amputated extremity because the neural pathways representing that limb remain active.

♦️ Phantom sensations can occur without pain, but when the sensations are painful they are classified as a neuropathic pain syndrome.

♦️ Management may include medications used for neuropathic pain, along with approaches such as mirror therapy or desensitization techniques when appropriate.

♦️ The defining feature is pain caused by altered nerve processing, making neuropathic pain the best classification.

Answer 4

Correct Answers:

2

Rationale :

✅ Formula

Tablets per dose = (Total daily dose ÷ Number of doses) ÷ Dose per tablet

✏️ Ordered = 2 g/day

✏️ Frequency = 2 doses/day

✏️ Available = 500 mg/tablet

✏️ 2 g × 1,000 = 2,000 mg/day

✏️ 2,000 mg ÷ 2 doses = 1,000 mg/dose

✏️ 1,000 mg ÷ 500 mg/tablet

= 2 tablets

Answer 5

Correct Answers:

Lower the height of the solution container.

Rationale :

🎯 Abdominal cramping during an enema commonly occurs when the solution enters the colon too rapidly.

🎯 The flow rate of an enema is influenced by the height of the solution container above the client's rectum.

🎯 Lowering the container decreases hydrostatic pressure, which slows the rate at which fluid enters the colon.

🎯 A slower infusion reduces rapid intestinal distention, helping relieve cramping and discomfort.

🎯 The nurse can temporarily slow or pause the flow until the cramping subsides and then continue at a slower rate.

🎯 The client should be encouraged to take slow, deep breaths to promote relaxation during the procedure.

🎯 Cramping alone does not necessarily indicate that the enema must be discontinued completely unless the pain becomes severe or another complication is suspected.

🎯 Therefore, lowering the solution container is the most appropriate action to reduce pressure, slow fluid administration, and relieve the client's discomfort.

Answer 6

Correct Answers:

Hypotension
Flat neck veins
Poor skin turgor

Rationale :

✅ Hypotension

🧿 Frequent vomiting and diarrhea cause substantial loss of water and electrolytes from the gastrointestinal tract.

🧿 Continued fluid loss decreases the client's intravascular circulating volume, producing hypovolemia.

🧿 As circulating volume falls, venous return and cardiac preload decrease.

🧿 Reduced preload can decrease stroke volume and cardiac output, resulting in hypotension.

🧿 The client may initially develop compensatory tachycardia as the body attempts to maintain adequate cardiac output.

🧿 The nurse should monitor blood pressure, including orthostatic changes, because worsening hypotension can indicate significant volume depletion.

✅ Flat neck veins

🧿 Neck vein assessment provides useful information about intravascular volume and right-sided cardiac filling pressure.

🧿 Significant gastrointestinal fluid loss reduces venous volume and central venous pressure.

🧿 Reduced venous return causes the jugular veins to appear flat or poorly distended.

🧿 This finding is consistent with hypovolemia rather than fluid volume excess.

🧿 Distended neck veins would suggest increased venous pressure and are more characteristic of conditions such as fluid overload or right-sided heart failure.

🧿 Flat neck veins therefore support the presence of fluid volume deficit caused by prolonged vomiting and diarrhea.

✅ Poor skin turgor

🧿 Poor skin turgor is a classic physical manifestation associated with dehydration and fluid volume deficit.

🧿 Loss of body water decreases the amount of fluid within the interstitial tissues.

🧿 The skin consequently becomes less elastic and may return slowly after being gently pinched.

🧿 Older adults naturally have reduced skin elasticity, so turgor should be interpreted carefully and assessed at an appropriate site such as the sternum or forehead.

🧿 Additional dehydration findings can include dry mucous membranes, thirst, decreased urine output, tachycardia, and weakness.

🧿 Three days of vomiting and diarrhea makes poor skin turgor an expected manifestation of significant fluid loss.

Answer 7

Correct Answers:

The client grimaces when they move.

Rationale :

🌼 Grimacing is an objective indicator of pain because it can be directly observed by the nurse.

🌼 Objective findings are signs that can be seen, measured, or verified by another person.

🌼 Facial expressions such as grimacing, guarding, moaning, or protective movements can suggest that the client is experiencing discomfort.

🌼 These behaviors are especially useful when the client has difficulty communicating or describing pain.

🌼 Objective indicators can support the nurse’s assessment, but they do not replace the client’s own pain report.

🌼 Pain is fundamentally a subjective experience, so the client’s description remains the most reliable source when they can communicate.

🌼 The nurse should assess both observed behaviors and the client’s stated pain characteristics to obtain a complete picture.

🌼 Because grimacing is directly observable, it is the best example of an objective pain manifestation.

Answer 8

Correct Answers:

Respiratory acidosis

Rationale :

✏️ COPD can impair effective alveolar ventilation, especially as the disease becomes more severe.

✏️ Reduced ventilation causes the client to retain carbon dioxide (CO₂) in the bloodstream.

✏️ Increased PaCO₂ raises the amount of carbonic acid in the blood and lowers the pH.

✏️ This produces respiratory acidosis, characterized by a low pH and elevated PaCO₂.

✏️ Clients with chronic COPD may develop renal compensation, with the kidneys retaining bicarbonate to help buffer the excess acid.

✏️ This compensation can bring the pH closer to normal even when PaCO₂ remains chronically elevated.

✏️ Worsening hypoventilation can overwhelm compensation and lead to acute-on-chronic respiratory acidosis.

✏️ The nurse should monitor ABG values, respiratory effort, mental status, and oxygenation for signs of worsening CO₂ retention.

Answer 9

Correct Answers:

Reflex Incontinence

Rationale :

🖊️ Reflex incontinence occurs when neurologic damage disrupts normal voluntary control of the bladder.

🖊️ A spinal cord injury can interrupt communication between the bladder, spinal cord, and brain.

🖊️ The bladder may then contract automatically when it reaches a certain volume, causing involuntary urine leakage.

🖊️ The client may have little or no awareness of the need to urinate before bladder emptying occurs.

🖊️ This pattern is sometimes associated with a neurogenic bladder caused by neurologic impairment.

🖊️ Bladder assessment can include urinary pattern, residual urine volume, infection symptoms, and the client's neurologic status.

🖊️ Management may involve scheduled bladder emptying, intermittent catheterization, or other interventions depending on the type of neurogenic dysfunction.

🖊️ Urinary leakage directly associated with nerve damage following spinal cord injury therefore most strongly indicates reflex incontinence.

Answer 10

Correct Answers:

11.2 mL per dose

Rationale :

✏️ The child weighs 33 lb, so the first step is converting pounds to kilograms because the prescription is written in mg/kg/day.

✏️ 33 lb ÷ 2.2 = 15 kg.

✏️ The prescribed daily dose is 150 mg/kg/day, so 15 kg × 150 mg/kg/day = 2,250 mg/day.

✏️ The medication is ordered every 6 hours, which means the child receives 4 doses per day.

✏️ 2,250 mg/day ÷ 4 doses = 562.5 mg per dose.

✏️ The available concentration is 250 mg in 5 mL, which equals 50 mg/mL.

✏️ 562.5 mg ÷ 50 mg/mL = 11.25 mL per dose.

✏️ Rounded appropriately, the nurse should administer 11.2 mL per dose.
