Correct Answer: C

Rationale: The Trousseau�s sign test is used to identify low calcium levels in a patient. This test involves inflating a blood pressure cuff on the patient's arm above systolic pressure for a few minutes, which can trigger a carpal spasm (wrist and hand flexion) in patients with low calcium levels (hypocalcemia). This is due to increased neuromuscular irritability caused by low calcium levels. Therefore, conducting a Trousseau�s sign test is the appropriate action to identify a low calcium level in a patient. Palpating turgor of skin, observing the color of the skin, and saving urine to measure 17-ketosteroids are not relevant actions for assessing calcium levels.

Correct Answer: B

Rationale: Duplex venous ultrasonography is the most accurate tool for assessing and diagnosing venous thrombosis. It is a non-invasive imaging technique that combines Doppler flow studies with conventional ultrasonography. This allows for the visualization of blood flow in the veins and identification of any blood clots or obstructions. Duplex venous ultrasonography is highly sensitive and specific for detecting deep vein thrombosis (DVT) in the lower extremities, making it the preferred imaging modality for diagnosing venous thrombosis. Other imaging modalities like ascending contrast venography, magnetic resonance imaging, and plethysmography are less commonly used due to their disadvantages compared to duplex venous ultrasonography such as invasiveness, cost, and lower accuracy.

Correct Answer: A

Rationale: A blood pressure of 142/92 mmHg in a client in the third trimester of pregnancy is elevated and could indicate the development of preeclampsia, a serious hypertensive disorder that can have adverse effects on both the mother and the fetus. Preeclampsia is characterized by high blood pressure accompanied by signs of organ damage, such as proteinuria and changes in other laboratory values. Immediate intervention is required in this situation, as preeclampsia can lead to complications such as seizures (eclampsia), stroke, and placental abruption. It is essential for the nurse to further assess the client and notify the healthcare provider promptly for appropriate management.

Correct Answer: B

Rationale: A client with sepsis and a temperature of 40�C is likely experiencing a systemic inflammatory response, which can lead to a variety of dysrhythmias. In this case, the client is more likely to develop a tachydysrhythmia (fast heart rate) due to the body's response to the infection. Sepsis can result in an increase in heart rate as the body tries to maintain adequate perfusion to vital organs in response to the inflammatory process. Tachydysrhythmias such as supraventricular tachycardia or atrial fibrillation are commonly observed in septic patients with high fevers.

Correct Answer: C

Rationale: Enalapril is an angiotensin-converting enzyme (ACE) inhibitor commonly used in the treatment of heart failure. One of the potential adverse effects of ACE inhibitors, including enalapril, is hypotension or low blood pressure. This is especially a concern following the initial administration of the drug, as it can cause a significant drop in blood pressure. Nurses should assess the patient for signs and symptoms of hypotension, such as dizziness, light-headedness, weakness, or fainting, after starting enalapril therapy. Monitoring blood pressure regularly and educating the patient about the possibility of low blood pressure is important to ensure patient safety and optimal outcomes.
