Correct Answer: D

Rationale: In hyperkalemia, cardiac arrhythmias are the most critical and life-threatening manifestation that requires immediate intervention. Hyperkalemia can lead to dangerous heart rhythm disturbances, potentially resulting in cardiac arrest. Prompt treatment is essential to stabilize the heart rhythm and prevent life-threatening complications.

Correct Answer: A

Rationale: Morphine, as a strong opioid agonist, has the highest likelihood of causing serious respiratory depression due to its potent effects on the central nervous system. While Pentazocine and Hydrocodone can also cause respiratory depression, they are less likely to do so compared to morphine. Nalmefene, an opioid antagonist, is used to reverse respiratory depression caused by opioids rather than causing it.

Correct Answer: C

Rationale: Placing an infant diagnosed with gastroesophageal reflux in a car seat after feeding can increase the risk of reflux and aspiration. The semi-upright or high Fowler position is recommended to help reduce reflux symptoms during feeding. Adding rice cereal to formula can help thicken it and reduce reflux episodes. Administering ranitidine using a syringe is a common method of oral medication administration.

Correct Answer: C

Rationale: Nifedipine primarily acts as a calcium channel blocker. It lacks significant effects on the calcium channels of the heart, making it ineffective for treating dysrhythmias like Atrial Fibrillation. Nifedipine is commonly used in conditions such as angina pectoris, essential hypertension, and vasospastic angina due to its vasodilatory effects and anti-anginal properties.

Correct Answer: B

Rationale: If diuresis has not occurred with corticosteroids in nephrotic syndrome, a diuretic like Furosemide (Lasix) is the appropriate choice to promote diuresis. Furosemide works by increasing urine production and reducing fluid retention. While Ibuprofen is an anti-inflammatory agent, it does not directly induce diuresis. Ciprofloxacin is an antibiotic and is not indicated for promoting diuresis in this scenario. Cyclophosphamide is an immunosuppressant, not an antisuppressant, and is not typically used to induce diuresis in nephrotic syndrome.
