Question

A nurse is caring for a client who has an elevated potassium level and is on a cardiac monitor. The nurse is aware that hyperkalemia may be associated with changes to the T-wave. On the graphic, point and click on the area of the electrocardiogram (ECG) that represents the T-wave.

(Selectable areas, or "Hot Spots," can be found by moving your cursor over the artwork until the cursor changes appearance, usually into a hand. Click only on the Hot Spot that corresponds to your answer)

Answer 1

Rationale :

❤️ The nurse should select the rounded wave that appears after the QRS complex.

❤️ On an ECG tracing, the T-wave is the final upward deflection after the QRS complex before the next P-wave begins.

❤️ The T-wave represents ventricular repolarization, meaning the ventricles are recovering electrically after contraction.

❤️ In hyperkalemia, the T-wave becomes tall, narrow, and peaked (“tented T-waves”) due to increased potassium affecting cardiac conduction.

❤️ Severe hyperkalemia can progress to widened QRS complexes, loss of P-waves, dangerous dysrhythmias, and cardiac arrest.

❤️ The nurse should monitor the ECG closely and report significant rhythm changes promptly.

Answer 2

Correct Answers:

nuchal rigidity

Rationale :

🧠 Nuchal rigidity is the correct answer because it refers to stiffness of the neck with difficulty bending the neck forward.

🧠 It occurs due to irritation of the meninges, the protective membranes surrounding the brain and spinal cord.

🧠 Nuchal rigidity is a classic assessment finding associated with meningitis.

🧠 The nurse should assess for additional neurological signs, including headache, fever, altered mental status, and photophobia.

🧠 Recognizing this finding early is important because meningitis can rapidly become life-threatening.

🧠 The nurse should report this finding promptly and continue neurological monitoring.

🧠 Nuchal rigidity differs from general muscle discomfort because the client has difficulty flexing the neck due to meningeal irritation.

🧠 Therefore, stiffness of the neck with inability to bend the neck is called nuchal rigidity.

Answer 3

Correct Answers:

Place the client on bed rest with the side rails up and the call bell in reach.

Rationale :

💊 Placing the client on bed rest with side rails up and the call bell within reach is the correct action after administering pre-anesthetic medication because these medications can cause sedation, dizziness, and impaired coordination.

💊 The client is at increased risk for falls and injury due to decreased alertness and motor control.

💊 Safety measures should be implemented immediately after administering sedating medications.

💊 Keeping the bed in a safe position and ensuring access to the call bell reduces the chance that the client will attempt to ambulate without assistance.

💊 The nurse should continue monitoring the client’s level of consciousness, respiratory status, and vital signs.

💊 Pre-anesthetic medications are intended to reduce anxiety and prepare the client for anesthesia, but they also affect the central nervous system.

💊 Maintaining a safe environment is the priority after medication administration.

💊 Therefore, the nurse should place the client on bed rest with side rails up and the call bell in reach.

Answer 4

Correct Answers:

Weight gain, especially in the face, neck, and trunk

Rationale :

🦋 Weight gain in the face, neck, and trunk is the correct answer because Cushing’s syndrome results from excess cortisol production.

🦋 High cortisol levels cause abnormal fat redistribution, leading to moon face, central/truncal obesity, and a buffalo hump on the upper back.

🦋 Cortisol also promotes protein breakdown, which contributes to thin extremities and muscle weakness.

🦋 Clients may also develop hyperglycemia, hypertension, fragile skin, easy bruising, and increased infection risk.

🦋 Recognizing these characteristic body changes helps the nurse identify possible cortisol excess.

🦋 Assessment should include weight changes, blood pressure, glucose levels, skin integrity, and muscle strength.

🦋 Early identification supports appropriate treatment and management of complications.

🦋 Therefore, the expected symptom of Cushing’s syndrome is weight gain, especially in the face, neck, and trunk.

Answer 5

Correct Answers:

Anorexia

Rationale :

❤️ Anorexia is the correct answer because loss of appetite is a common early manifestation of digoxin toxicity, especially in older adults.

❤️ Digoxin toxicity affects the gastrointestinal system and may cause anorexia, nausea, vomiting, and abdominal discomfort.

❤️ Older adults are at increased risk because of age-related changes in kidney function, which can reduce digoxin clearance and increase medication levels.

❤️ The nurse should monitor for additional toxicity signs, including confusion, weakness, visual disturbances, and cardiac dysrhythmias.

❤️ Before administering digoxin, the nurse should assess the client’s apical pulse and monitor serum digoxin levels as prescribed.

❤️ Low potassium levels can increase the risk of digoxin toxicity, so electrolyte monitoring is important.

❤️ Early recognition of toxicity helps prevent serious complications such as life-threatening cardiac rhythms.

❤️ Therefore, anorexia is the finding associated with digoxin toxicity.

Answer 6

Correct Answers:

Famotidine (Pepcid)
Cimetidine (Tagamet)
Omeprazole (Prilosec)
Pantoprazole (Protonix)

Rationale :

Famotidine (Pepcid)

🩺 Famotidine is an H2 receptor antagonist used to treat GERD by reducing stomach acid production.

🩺 It blocks histamine stimulation of gastric parietal cells, decreasing hydrochloric acid secretion.

🩺 Lower acid levels reduce irritation and inflammation of the esophagus.

🩺 It is commonly used for symptom relief in clients with acid reflux.

🩺 The nurse should teach clients to take the medication as prescribed and report persistent symptoms.

Cimetidine (Tagamet)

🩺 Cimetidine is also an H2 receptor antagonist that decreases gastric acid secretion.

🩺 It can help relieve GERD symptoms by reducing acid exposure in the esophagus.

🩺 It is less commonly used today due to medication interactions but remains an acid-reducing medication.

🩺 It is classified as a medication used in GERD management.

Omeprazole (Prilosec)

🩺 Omeprazole is a proton pump inhibitor (PPI) used to treat GERD.

🩺 PPIs block the final step of acid secretion in gastric parietal cells, producing stronger acid suppression than H2 blockers.

🩺 They promote healing of acid-related esophageal irritation.

🩺 They are commonly prescribed for frequent or severe GERD symptoms.

Pantoprazole (Protonix)

🩺 Pantoprazole is a proton pump inhibitor (PPI) used to decrease gastric acid secretion.

🩺 It is commonly prescribed for GERD, erosive esophagitis, and other acid-related disorders.

🩺 It promotes symptom relief by reducing acid exposure to the esophagus.

🩺 The nurse should monitor long-term PPI therapy for potential nutrient deficiencies and other complications.

Answer 7

Correct Answers:

"I plan to slow down if I am tired the day after exercising."

Rationale :

❤️ Slowing down activity when experiencing fatigue after exercise indicates effective teaching because clients with heart failure need to balance activity with rest.

❤️ Exercise should be performed according to tolerance, and increased fatigue can indicate that the heart is not tolerating the current activity level.

❤️ The client should gradually increase activity and recognize signs that require reduced exertion.

❤️ Energy conservation helps prevent excessive workload on the heart and reduces symptoms such as fatigue and shortness of breath.

❤️ Clients with heart failure should remain active but avoid overexertion.

❤️ Monitoring response to activity helps guide safe exercise planning.

❤️ This statement demonstrates that the client understands the importance of listening to their body and adjusting activity appropriately.

❤️ Therefore, this statement indicates effective discharge teaching.

Answer 8

Correct Answers:

Prothrombin time (PT)

Rationale :

🩸 Prothrombin time (PT) is the correct laboratory value to monitor for a therapeutic effect of warfarin therapy.

🩸 Warfarin works by inhibiting vitamin K–dependent clotting factors (II, VII, IX, and X), which prolongs the time needed for blood to clot.

🩸 PT measures the effectiveness of warfarin by evaluating the extrinsic and common coagulation pathways.

🩸 The nurse should also monitor the international normalized ratio (INR), which standardizes PT results and is commonly used to adjust warfarin dosing.

🩸 Clients with artificial heart valves require anticoagulation to prevent thrombus formation on the valve.

🩸 The nurse should assess for signs of bleeding, such as bruising, hematuria, bleeding gums, or unusual bleeding.

🩸 Maintaining PT/INR within the prescribed therapeutic range helps balance prevention of clots with prevention of hemorrhage.

🩸 Therefore, the nurse should monitor prothrombin time (PT).

Answer 9

Correct Answers:

Allopurinol

Rationale :

🦵 Allopurinol is the correct answer because it is commonly used to reduce serum uric acid levels in clients with gout or hyperuricemia.

🦵 Allopurinol works by inhibiting xanthine oxidase, an enzyme involved in the production of uric acid.

🦵 Lowering uric acid levels helps prevent the formation of urate crystals that cause painful gout attacks.

🦵 It is commonly used for long-term prevention of gout flares rather than immediate relief of acute pain.

🦵 The nurse should teach clients to take the medication as prescribed and report signs of hypersensitivity, such as rash.

🦵 Adequate hydration is often encouraged to help reduce the risk of kidney stone formation.

🦵 Monitoring serum uric acid levels helps evaluate treatment effectiveness.

🦵 Therefore, allopurinol is the medication used to reduce serum uric acid levels.
