Correct Answer: A

Rationale: During vomiting in a client with an NGT, it is essential for the nurse to direct the UAP to measure the emesis to monitor the output. This helps in assessing the client's condition and response to treatment. Meanwhile, irrigating the NGT can be beneficial to relieve any obstruction that might be contributing to the vomiting. Stopping the NGT feed and notifying the healthcare provider (choice B) is important but not the immediate action needed. Increasing the NGT suction pressure (choice C) is unnecessary and can lead to complications. Elevating the head of the bed (choice D) is a general intervention to prevent aspiration but may not address the immediate issue of managing the vomiting episode and potential tube obstruction.

Correct Answer: A

Rationale: The correct answer is A. Hemabate can cause severe nausea, vomiting, or diarrhea, so administering the prescribed antiemetic can help manage these side effects. Choice B is incorrect as there is no indication in the scenario to administer IV fluids. Choice C is not the priority at this stage as the client's condition does not necessitate an immediate blood transfusion. Choice D is unnecessary every 5 minutes; monitoring vital signs should be done but not at such a high frequency.

Correct Answer: A

Rationale: Clonidine can lower blood pressure, so a BP of 90/76 mm Hg may indicate that it is unsafe to administer another dose. In this situation, the low blood pressure reading indicates that the client is already experiencing hypotension, which is a common side effect of clonidine. Administering more clonidine could further lower the blood pressure, leading to potential complications. The heart rate, respiratory rate, and temperature are within normal limits and do not serve as contraindications for administering clonidine in this scenario.

Correct Answer: C

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.

Correct Answer: A

Rationale: The correct action for the nurse to implement is to observe for unilateral swelling. Unilateral swelling could indicate a deep vein thrombosis (DVT), which is a serious complication that requires immediate assessment. Administering pain medication or applying warm compress may not address the underlying cause of the symptoms. Notifying the healthcare provider should be done after assessing and identifying the issue of unilateral swelling.
