A nurse is caring for a client who has deep-vein thrombosis (DVT) and is receiving heparin therapy. Which of the following laboratory values indicates that the client's heparin therapy is effective?

Correct Answer: A

Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.

Correct Answer: B

Rationale: The correct intervention for a client with acute diverticulitis is to initiate a low-fiber diet. A low-fiber diet helps manage acute diverticulitis by reducing irritation to the colon, allowing it to heal. Administering a cleansing enema (Choice A) can worsen diverticulitis by increasing pressure within the colon. Applying moist heat to the abdomen (Choice C) may provide comfort but does not address the underlying cause. Providing a clear liquid diet (Choice D) is not ideal for diverticulitis management as it lacks the necessary nutrients for healing and may not provide enough bulk to prevent further irritation.

Correct Answer: D

Rationale: The correct answer is D. Clients taking furosemide should avoid alcohol because it can lead to dehydration and potential interactions with the medication. Choices A and B are incorrect because furosemide is a diuretic that can actually lower potassium levels, so the client should not expect an increase in potassium levels or solely rely on bananas for potassium intake. Choice C is incorrect because a cough is not a common side effect of furosemide and should not be a reason to stop taking the medication.

Correct Answer: C

Rationale: The correct action for the nurse to take is to limit IV exposure to light. Nitroprusside is light-sensitive, and exposure to light can lead to its degradation, potentially reducing its efficacy in treating severe hypertension. Keeping calcium gluconate at the bedside (Choice A) is not directly related to managing nitroprusside infusion. While monitoring blood pressure every 2 hours (Choice B) is important in managing hypertension, it is not the immediate action required to ensure medication efficacy. Attaching an inline filter to the IV tubing (Choice D) may help filter particles but does not address the critical concern of light sensitivity associated with nitroprusside administration.

Correct Answer: C

Rationale: Providing high-calorie snacks is essential when caring for a client in the manic phase of bipolar disorder because they often have increased energy expenditure and may not eat adequately due to their heightened activity levels. Encouraging group activities (Choice A) may overwhelm the client further during this phase. Encouraging frequent naps (Choice B) contradicts the need to manage increased energy levels. Promoting physical activity during mealtimes (Choice D) may not be appropriate as it can distract the client from eating, which is crucial in meeting their nutritional needs.

Correct Answer: B

Rationale: After a total hip arthroplasty, it is crucial to prevent hip dislocation. Placing an abduction pillow between the client's legs helps maintain proper alignment of the hip joint and prevents adduction, which could lead to dislocation. Therefore, choice B is the correct action. Choice A is incorrect because positioning the client supine with a pillow between the legs does not provide the necessary abduction to prevent dislocation. Choice C, placing a pillow under the client's knees, does not address the need for abduction. Choice D, positioning the client's legs in adduction, is incorrect as adduction increases the risk of hip dislocation following hip arthroplasty.

Correct Answer: B

Rationale: The correct answer is B. Limiting potassium-rich foods is crucial for clients with chronic kidney disease to prevent hyperkalemia, a common complication. Increasing intake of potassium-rich foods like bananas (choice A), protein-rich foods (choice C), or dairy products (choice D) can exacerbate hyperkalemia in these clients. Bananas, protein-rich foods, and dairy products are all high in potassium, which is detrimental for individuals with chronic kidney disease. Therefore, choices A, C, and D are incorrect.

Correct Answer: A

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to lie down before taking the medication. Nitroglycerin can cause a sudden drop in blood pressure leading to dizziness or fainting, so taking the medication while lying down helps prevent falls. Choice B is incorrect because nitroglycerin is usually taken on an empty stomach to enhance its absorption. Choice C is incorrect as taking a double dose of nitroglycerin can lead to low blood pressure and other adverse effects. Choice D is incorrect as nitroglycerin sublingual tablets should be stored in their original container at room temperature away from light and moisture, not in the refrigerator.

Correct Answer: C

Rationale: The correct answer is C: 'Numbness and tingling of the fingers.' Post-thyroidectomy, hypocalcemia is a concern due to potential damage to the parathyroid glands that regulate calcium levels. Numbness and tingling of the fingers are classic signs of hypocalcemia. Constipation (Choice A) is not typically associated with hypocalcemia. Frequent urination (Choice B) is more indicative of conditions like diabetes or a urinary tract infection. Increased thirst (Choice D) is commonly seen in conditions such as diabetes insipidus or uncontrolled diabetes mellitus, not specifically related to hypocalcemia.
