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: C

Rationale: The correct action the nurse should take when caring for a client experiencing acute alcohol withdrawal is to administer lorazepam as prescribed. Lorazepam is a benzodiazepine used to prevent seizures and manage agitation in clients undergoing alcohol withdrawal. Administering haloperidol (Choice A) is not recommended in alcohol withdrawal as it may lower the seizure threshold. Keeping the client in a supine position (Choice B) is not specifically indicated in managing alcohol withdrawal. Encouraging the client to drink fluids with meals (Choice D) is important for hydration but does not address the acute symptoms of alcohol withdrawal.

Correct Answer: C

Rationale: The correct answer is C. A serum potassium level of 3.2 mEq/L indicates hypokalemia, a potential complication of furosemide therapy, and should be reported immediately. Hypokalemia can lead to serious cardiac dysrhythmias. Choices A, B, and D are important assessments but are not as critical as managing serum potassium levels in a client receiving furosemide for heart failure.

Correct Answer: A

Rationale: The correct answer is to administer anticoagulants. Administering anticoagulants is crucial in the management of deep vein thrombosis (DVT) as it helps prevent the clot from growing larger or dislodging, potentially causing a life-threatening pulmonary embolism. While monitoring oxygen levels, applying compression stockings, and encouraging ambulation are important aspects of DVT management, administering anticoagulants is the most critical intervention to prevent further complications.

Correct Answer: A

Rationale: The correct answer is to 'Check daily weight.' Monitoring daily weight is the most accurate method to assess for fluid overload in patients with heart failure. Weight gain can indicate fluid retention, a common issue in heart failure patients. Checking blood pressure (Choice B) can provide information about hemodynamic status but may not be as specific for fluid overload as monitoring weight. Monitoring heart sounds (Choice C) can provide information about cardiac function but may not directly assess fluid overload. Assessing for jugular vein distention (Choice D) can be a sign of increased central venous pressure but may not always correlate with fluid overload as accurately as daily weight checks.

Correct Answer: C

Rationale: Changing the entire pouching system weekly is essential for maintaining skin integrity and preventing infection. Option A is incorrect as applying a skin barrier should be done during the pouch change, not separately. Option B is incorrect as ileostomy pouches should be emptied when they are one-third to one-half full to prevent leakage. Option D is incorrect because cleansing the peristomal skin with alcohol can be too harsh and may cause skin irritation.

Correct Answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, ensuring adequate oxygenation is the priority. Administering oxygen helps improve oxygen levels, which is crucial for the patient's well-being. Repositioning the patient, administering bronchodilators, or giving IV fluids are important interventions in certain situations, but when a patient is in respiratory distress, providing oxygen takes precedence over other actions.

Correct Answer: A

Rationale: Administering oxygen is the initial step in managing chest pain. Oxygen helps improve oxygenation levels in the blood, which is crucial in cases of chest pain. Repositioning the patient, providing pain relief, or administering nitroglycerin may be necessary steps depending on the underlying cause, but administering oxygen takes precedence as it addresses the primary concern of oxygen supply to the body during chest pain.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Administering anticoagulants is the most appropriate nursing intervention for a patient with suspected DVT because it helps prevent further clot formation and complications. Applying compression stockings (choice B) can be a preventive measure but is not the primary intervention for treating DVT. Encouraging ambulation (choice C) is beneficial for preventing DVT but is not the immediate intervention for a suspected case. Monitoring oxygen saturation (choice D) is important for assessing respiratory function but is not the primary intervention for DVT treatment.
