The nurse is caring for a client with chronic heart failure who is receiving digoxin therapy. The nurse reviews the client's lab results and notes that the serum potassium level is 3.0 mEq/L. What action should the nurse take next?
- A. Administer a potassium supplement
- B. Notify the healthcare provider
- C. Hold the next dose of digoxin
- D. Increase dietary potassium intake
Correct Answer: C
Rationale: In clients receiving digoxin therapy, low potassium levels can increase the risk of digoxin toxicity. Therefore, when the nurse notes a serum potassium level of 3.0 mEq/L, it is crucial to hold the next dose of digoxin. Notifying the healthcare provider is essential to ensure appropriate interventions, such as potassium supplementation, can be implemented. Administering a potassium supplement without healthcare provider guidance may lead to rapid potassium level changes and potential adverse effects. Increasing dietary potassium intake alone may not promptly address the low serum potassium level in this acute situation.

A male client with HIV receiving saquinavir PO in combination with other antiretrovirals reports constant hunger and thirst but is losing weight. What action should the nurse implement?
- A. Use a glucometer to check glucose level.
- B. Teach client to measure weight accurately.
- C. Explain that medication dose may need to be increased.
- D. Reassure client weight will increase as viral load decreases.
Correct Answer: A
Rationale: The correct action for the nurse to implement is to use a glucometer to check the client's glucose level. Saquinavir, an HIV medication, can lead to hyperglycemia, which may cause symptoms like constant hunger and thirst while losing weight. Checking the glucose level will help assess for hyperglycemia. Choice B is not the priority in this situation as the client's weight loss is a concerning symptom that needs immediate attention. Choice C is incorrect because increasing the medication dose without assessing the glucose level first could exacerbate hyperglycemia. Choice D is incorrect as it does not address the symptoms of constant hunger, thirst, and weight loss, which may indicate a more urgent issue like hyperglycemia.
The nurse is instructing a 65-year-old female client diagnosed with osteoporosis. The most important instruction regarding exercise would be to
- A. Exercise doing weight-bearing activities
- B. Exercise to reduce weight
- C. Avoid exercise activities that increase the risk of fracture
- D. Exercise to strengthen muscles and thereby protect bones
Correct Answer: A
Rationale: Weight-bearing exercises are crucial in managing osteoporosis as they help strengthen bones. Choice A is the correct answer because weight-bearing activities, such as walking, dancing, or weight training, help stimulate bone formation and strengthen bones, which is essential in managing osteoporosis. Choice B is incorrect as the primary focus should be on the type of exercise rather than weight reduction. Choice C is incorrect because avoiding exercise altogether can lead to further bone density loss, and it is important to engage in safe weight-bearing activities. Choice D is incorrect as the primary goal of exercise in osteoporosis is to improve bone density through weight-bearing activities.
The nurse is providing care for a client with severe peripheral arterial disease (PAD). The client reports a history of rest ischemia, with leg pain that occurs during the night. Which action should the nurse take in response to this finding?
- A. Elevate the legs on pillows
- B. Encourage ambulation and leg exercises
- C. Provide a heating pad for warmth
- D. Offer cold packs when the pain occurs
Correct Answer: C
Rationale: Providing warmth can help dilate peripheral vessels and increase blood flow, relieving ischemic pain. In PAD, where there is already compromised blood flow, elevating the legs or applying cold therapy could worsen ischemic pain by further reducing blood flow to the extremities. Encouraging ambulation and leg exercises may be beneficial in other conditions but not suitable for clients with severe PAD experiencing rest ischemia.
A client with chronic kidney disease is prescribed erythropoietin. What lab value should the nurse monitor to evaluate the effectiveness of the therapy?
- A. White blood cell count.
- B. Hemoglobin level.
- C. Serum creatinine level.
- D. Platelet count.
Correct Answer: B
Rationale: Erythropoietin therapy stimulates red blood cell production in clients with chronic kidney disease. Hemoglobin levels should be monitored to assess the effectiveness of the therapy and ensure the client is not developing anemia. Increased hemoglobin levels indicate successful treatment, whereas very high levels may suggest erythropoietin is overcorrecting the anemia. Monitoring the white blood cell count is not directly related to erythropoietin therapy for anemia. Serum creatinine level is used to assess kidney function rather than the effectiveness of erythropoietin therapy. Platelet count is not typically affected by erythropoietin therapy and is not a key indicator of its effectiveness.
A client with type 1 diabetes reports blurry vision. What is the most important assessment the nurse should perform?
- A. Assess the client's most recent blood glucose levels.
- B. Check the client's hemoglobin A1C level.
- C. Check the client's blood pressure for signs of hypertension.
- D. Examine the client's feet for signs of neuropathy.
Correct Answer: A
Rationale: Blurry vision in clients with type 1 diabetes may indicate hyperglycemia, which requires prompt assessment of recent blood glucose levels to determine the cause and appropriate intervention. Checking the client's hemoglobin A1C level (Choice B) is useful for assessing long-term glucose control, not for immediate management of blurry vision. Monitoring blood pressure (Choice C) is important in diabetes care but is not the most crucial assessment when blurry vision is reported. Examining the client's feet for signs of neuropathy (Choice D) is important in diabetic foot care but is not the priority when dealing with blurry vision.
