Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Administering anticoagulants is crucial in managing patients with suspected DVT as it helps prevent further clot formation and reduces the risk of complications like pulmonary embolism. Choice B, applying compression stockings, is more focused on preventing DVT in high-risk patients rather than managing an established case. Encouraging ambulation, choice C, is beneficial in the prevention of DVT but is not the primary management for suspected cases. Monitoring oxygen saturation, choice D, is important in overall patient care but is not the primary intervention for suspected DVT.

Correct Answer: C

Rationale: Checking the client's blood glucose level every 4 hours is essential when managing a client on TPN to monitor for hyperglycemia, a common complication. Monitoring urine output (Choice A) is important but not a priority in this scenario. Administering a bolus of 0.9% sodium chloride (Choice B) is not indicated as it is unrelated to managing TPN. Flushing the TPN line with sterile water (Choice D) is necessary, but it should be done with 0.9% sodium chloride, not water.

Correct Answer: D

Rationale: In a client with a history of angina experiencing chest pain radiating to the left arm, obtaining a 12-lead ECG is the priority action to assess for myocardial infarction. An ECG helps in diagnosing and evaluating the extent of cardiac ischemia or infarction. Administering nitroglycerin, oxygen, or aspirin can follow once the ECG has been performed to confirm the diagnosis and guide further interventions. Administering nitroglycerin sublingually is often appropriate for angina but should not precede the ECG in this urgent scenario. Oxygen therapy and aspirin administration are important interventions but obtaining the ECG takes precedence in assessing for acute cardiac events.

Correct Answer: A

Rationale: The correct answer is hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss through increased urinary excretion, making hypokalemia the most concerning electrolyte imbalance. Hyponatremia (Choice B) is not typically associated with furosemide use. Hyperkalemia (Choice C) is less likely due to furosemide's potassium-wasting effect. Hypercalcemia (Choice D) is not a common electrolyte imbalance seen with furosemide.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid consuming alcohol while taking this medication.' Clients taking metformin should avoid alcohol as it increases the risk of lactic acidosis. Choice A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Choice C is incorrect as metformin is typically taken with meals, not at bedtime. Choice D is incorrect because muscle pain is not a common side effect of metformin.
