Nursing Elites

1. Which electrolyte imbalance is common in patients receiving diuretics?

• A. Hypokalemia
• B. Hypercalcemia
• C. Hyponatremia
• D. Hypermagnesemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

2. A client is receiving warfarin for atrial fibrillation. Which of the following laboratory tests should the nurse expect to be ordered to monitor the effect of warfarin?

• A. Platelet count
• B. International normalized ratio (INR)
• C. Prothrombin time (PT)
• D. Partial thromboplastin time (PTT)

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). When a client is on warfarin therapy, the INR is monitored regularly to assess the anticoagulant effects of the medication. A therapeutic INR range for most indications is between 2.0 to 3.0. Choices A, C, and D are not typically used to monitor the effect of warfarin. Platelet count assesses the number of platelets in the blood, PT measures the clotting time of plasma, and PTT evaluates the intrinsic pathway of coagulation.

3. A nurse is caring for a client who has a new prescription for nitroglycerin transdermal patches. Which of the following instructions should the nurse include?

• A. Apply the patch to the same location each time.
• B. Rotate the patch site daily to avoid skin irritation.
• C. Apply the patch in the morning and remove it at bedtime.
• D. Keep the patch on at all times, even during a bath.

Correct answer: C

Rationale: The correct answer is to apply the nitroglycerin transdermal patch in the morning and remove it at bedtime. This schedule helps prevent tolerance to the medication. Choice A is incorrect because the patch should be rotated to different sites to prevent skin irritation. Choice B is incorrect as daily rotation is recommended, not daily application to the same site. Choice D is incorrect as the patch should be removed during a bath as it may decrease the efficacy of the medication.

4. A nurse is caring for a client who has a pulmonary embolism. The nurse should identify which finding as an indication of effective treatment?

• A. A chest x-ray reveals increased density in all lung fields.
• B. The client reports feeling less anxious.
• C. Diminished breath sounds are auscultated bilaterally.
• D. ABG results include a pH of 7.48, PaO2 77 mm Hg, and PaCO2 47 mm Hg.

Correct answer: B

Rationale: The correct answer is B. The client reporting feeling less anxious is a positive indication of effective treatment for a pulmonary embolism. This suggests that the client's condition is improving psychologically. Option A is incorrect because increased density in all lung fields on a chest x-ray may indicate unresolved issues related to the embolism. Option C is incorrect as diminished breath sounds bilaterally suggest a complication or worsening of the condition. Option D is incorrect as ABG results within normal range do not necessarily indicate effective treatment for a pulmonary embolism, as other complications may still be present.

5. A client has a new prescription for metformin. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime.
• B. Avoid drinking alcohol while taking this medication.
• C. Eat 3 large meals each day.
• D. Report any muscle pain to your provider.

Correct answer: B

Rationale: The correct instruction the nurse should include for a client prescribed metformin is to avoid drinking alcohol. Alcohol consumption while on metformin increases the risk of lactic acidosis, a serious condition. Taking metformin at bedtime (choice A) is not a standard instruction. Eating 3 large meals each day (choice C) is not specific to metformin use and may not be suitable for all individuals. Reporting muscle pain (choice D) is important but not directly related to metformin use.
