Correct Answer: B

Rationale: The correct answer is B. Montelukast is a leukotriene receptor antagonist that is typically taken once daily in the evening for asthma management. Choice A is incorrect as montelukast is not used for acute asthma attacks but rather for the prevention of asthma symptoms. Choice C is also incorrect because montelukast can be taken with or without food. Choice D is misleading as all medications, including montelukast, have potential side effects.

Correct Answer: A

Rationale: A TPN solution with an oily appearance and a layer of fat on top indicates that the solution is 'cracked' and should not be used as it may have separated or deteriorated. This finding suggests a need to obtain a new bag of TPN before administering. Options B, C, and D are normal aspects of TPN administration. Option B confirms the presence of essential components in the TPN solution, option C provides information about the preparation time, and option D ensures proper identification and matching of the TPN with the correct client.

Correct Answer: B

Rationale: The correct answer is to assess the patient's heart rate. Levothyroxine is a thyroid hormone replacement medication that can increase metabolism. One of the potential side effects of levothyroxine is tachycardia (rapid heart rate). Therefore, it is essential for the healthcare provider to assess the patient's heart rate before administering the medication to monitor for any signs of tachycardia. Giving levothyroxine with food may affect its absorption, so it is typically recommended to administer it on an empty stomach. Administering it in the evening is not necessary unless specifically prescribed by the healthcare provider, and giving it with calcium supplements can interfere with the absorption of levothyroxine.

Rationale: The correct answer is B. Montelukast is a leukotriene receptor antagonist that is typically taken once daily in the evening for asthma management. Choice A is incorrect as montelukast is not used for acute asthma attacks but rather for the prevention of asthma symptoms. Choice C is also incorrect because montelukast can be taken with or without food. Choice D is misleading as all medications, including montelukast, have potential side effects.

Correct Answer: A

Rationale: Corrected Rationale: When a client is prescribed furosemide, the nurse should monitor serum potassium levels. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias. Choices B, C, and D are incorrect because furosemide primarily affects potassium excretion rather than liver function, blood glucose levels, or calcium levels.
