Correct Answer: B

Rationale: The correct answer is B because sitting at the bedside and asking if there is anything the patient needs demonstrates empathy and support. It allows the patient to express their concerns and fears, providing emotional comfort. It shows the nurse is actively listening and willing to help address any immediate needs or concerns. Choice A is incorrect because it dismisses the patient's feelings and may come across as invalidating. Choice C is incorrect because insisting that family members remain may not be what the patient needs at that moment and could cause additional stress. Choice D is incorrect because it does not address the patient's emotional distress and may not be true in the context of terminal illness.

Correct Answer: A

Rationale: The correct answer is A: Airway clearance therapies. In cystic fibrosis (CF), mucus buildup in the lungs can lead to infections and breathing difficulties. Airway clearance therapies help loosen and clear this mucus, improving lung function. Antibiotic therapy (B) is used to treat infections but is not specific to CF treatment. Nutritional support (C) is crucial in CF due to malabsorption, but it is not the primary treatment. Tracheostomy (D) is a surgical procedure to create an airway bypassing the upper respiratory tract and is not a standard treatment for CF.

Correct Answer: D

Rationale: The correct answer is D because the patient is exhibiting Cheyne-Stokes breathing pattern characterized by periods of apnea followed by deep and rapid breathing. The nurse should document this pattern accurately. Option A is incorrect as suctioning is not indicated. Option B may worsen the respiratory pattern. Option C is not specifically related to addressing the breathing pattern.

Correct Answer: A

Rationale: The correct answer is A: fluid retention of 1.5 liters. The weight gain from 97.5 kg to 99 kg indicates an increase in fluid retention. This difference of 1.5 kg corresponds to fluid retention of 1.5 liters, as 1 liter of water weighs approximately 1 kg. This weight gain suggests that the patient is retaining more fluid than they are excreting, leading to an increase in weight. Incorrect choices: B: fluid loss of 1.5 liters - This is incorrect because the weight increased, indicating fluid retention. C: equal intake and output due to insensible losses - This is incorrect as weight increased, showing an imbalance in intake and output. D: fluid loss of 0.5 liters - This is incorrect as the weight increased, indicating fluid retention, not loss.

Correct Answer: C

Rationale: The correct answer is C: Administer the dose as prescribed. Verapamil is a calcium channel blocker used to treat atrial flutter. The vital signs obtained are within normal range for this medication. A heart rate of 92 and blood pressure of 110/76 are not contraindications for administering verapamil. Option A is incorrect as calcium gluconate is not indicated in this situation. Option B is incorrect because the vital signs are stable and do not warrant withholding the medication. Option D is incorrect as there is no need to delay the administration of verapamil based on the vital signs provided.
