A client with diabetes mellitus is being taught by a nurse about managing blood glucose levels. Which of the following client statements indicates an understanding of the teaching?

Correct Answer: A

Rationale: Choice A is the correct answer because consuming a snack when the blood glucose level is below 70 mg/dL helps prevent hypoglycemia in clients with diabetes mellitus. Choice B is incorrect because taking insulin when blood glucose is high (above 200 mg/dL) helps manage hyperglycemia, not hypoglycemia. Choice C is incorrect as checking blood glucose levels once a week is insufficient for proper diabetes management, which typically requires more frequent monitoring. Choice D is incorrect because waiting for symptoms of hyperglycemia to take insulin can lead to uncontrolled blood glucose levels.

Correct Answer: D

Rationale: The correct answer is D. Urinary output greater than fluid intake could indicate diabetes insipidus, a complication following hypophysectomy. Diabetes insipidus is characterized by excessive urination and extreme thirst due to inadequate levels of antidiuretic hormone (ADH). Options A, B, and C are all expected findings in the immediate postoperative period following a hypophysectomy. A Glasgow Coma Scale score of 15 indicates the highest level of consciousness, blood drainage on the initial dressing is a common finding after surgery, and dry mouth can be a side effect of anesthesia and surgical procedures.

Correct Answer: A

Rationale: The correct instruction the nurse should include is to advise the client to avoid consuming foods high in vitamin K. Foods rich in vitamin K, such as leafy greens, can interfere with the effectiveness of warfarin, an anticoagulant medication. Therefore, it is important for clients on warfarin therapy to maintain consistent vitamin K intake to keep their INR levels stable. The other options are also important but not the priority in the context of warfarin therapy. Ingesting foods high in vitamin K can affect the medication's efficacy, making it crucial to highlight this dietary consideration during client education.

Correct Answer: C

Rationale: Encouraging the client to ambulate as soon as possible is essential in preventing complications like deep vein thrombosis post knee arthroplasty. While keeping the affected leg elevated and applying ice packs can be beneficial in certain situations, early ambulation takes precedence in this case. Performing range-of-motion exercises hourly may not be necessary and could potentially cause more harm than good if not done correctly or excessively.

Correct Answer: C

Rationale: The correct intervention for a client with dementia who is frequently agitated is to use a calm and reassuring approach when speaking to them. This approach helps reduce agitation and create a more therapeutic environment. Offering several choices may overwhelm the client and increase agitation, making choice A incorrect. Confronting the client can escalate the situation and worsen agitation, making choice B inappropriate. While encouraging stimulating activities is beneficial, it may not be the most effective intervention for immediate agitation management, making choice D less priority compared to using a calm and reassuring approach.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT (activated partial thromboplastin time) when a patient is receiving heparin therapy. aPTT monitoring is essential for assessing the therapeutic effectiveness of heparin, ensuring the patient is within the desired therapeutic range to prevent both clotting and bleeding. Monitoring platelet count (Choice B) is important for assessing for heparin-induced thrombocytopenia but is not the primary monitoring parameter for heparin therapy. Monitoring sodium levels (Choice C) and calcium levels (Choice D) are not directly related to assessing the therapeutic effectiveness or potential side effects of heparin therapy.

Correct Answer: B

Rationale: The correct answer is to monitor the client's respiratory rate. This assessment is crucial in the postoperative period to detect any respiratory complications such as hypoxia or respiratory distress. Assessing pain level (Choice A) is important but may not be the top priority as respiratory status takes precedence. Measuring blood pressure (Choice C) is also important but not as critical immediately postoperatively as monitoring respiratory function. Checking bowel sounds (Choice D) is relevant for assessing gastrointestinal function but is typically not the top priority in the immediate postoperative phase.

Correct Answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.

Correct Answer: B

Rationale: When administering enoxaparin, it is important to pinch the skin to ensure proper subcutaneous injection. Massaging the injection site after administering the medication is not recommended. Administering the medication at bedtime is not a specific requirement for enoxaparin. Aspirating before injecting the medication is not necessary for subcutaneous injections like enoxaparin.
