What is the most appropriate action when a patient is experiencing severe dehydration?

Correct Answer: A

Rationale: The most appropriate action when a patient is experiencing severe dehydration is to administer IV fluids. This intervention is crucial in rapidly correcting dehydration and restoring fluid balance. Encouraging oral fluids may not be sufficient in cases of severe dehydration where intravenous rehydration is needed. Monitoring electrolytes is important but administering fluids takes precedence in severe dehydration. Performing a neurological exam is not the primary intervention for severe dehydration.

Correct Answer: A

Rationale: Monitoring oxygen saturation is crucial in assessing a patient with respiratory distress because it helps determine if the patient is receiving adequate oxygen. Oxygen saturation levels provide immediate feedback on the efficiency of oxygen delivery to the tissues. Checking for abnormal breath sounds (Choice B) is relevant in respiratory assessments, but it is secondary to assessing oxygen saturation. Pitting edema (Choice C) and performing a neurological exam (Choice D) are not directly related to assessing respiratory distress and are not the primary focus when managing a patient with breathing difficulties.

Correct Answer: A

Rationale: The correct answer is to observe for facial expressions when assessing pain in a non-verbal patient. Facial expressions can provide vital clues about the patient's pain level and discomfort. Choices B and C, observing for restlessness and sweating, can be less specific and may indicate other issues besides pain. Choice D, checking for non-verbal cues, is too broad and does not specify the crucial aspect of focusing on facial expressions.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, commonly causes the loss of potassium in the urine, leading to hypokalemia. This electrolyte imbalance can result in various complications such as cardiac arrhythmias and muscle weakness. Choice B, Hyponatremia, is not typically associated with furosemide use. Choice C, Hyperkalemia, is the opposite of the expected electrolyte imbalance caused by furosemide. Choice D, Hypercalcemia, is not a common side effect of furosemide.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT in patients receiving heparin therapy. Activated Partial Thromboplastin Time (aPTT) is crucial to assess the therapeutic effectiveness of heparin and to prevent bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy, not heparin. Platelet count (Choice C) monitoring is essential for detecting heparin-induced thrombocytopenia rather than assessing heparin therapy itself. Monitoring sodium levels (Choice D) is not directly related to heparin therapy monitoring.
