Correct Answer: A

Rationale: The correct answer is A: A history of gastroesophageal reflux disease. Clients with gastroesophageal reflux disease have a higher risk of aspiration during tube feeding due to the potential for reflux of stomach contents into the lungs. This increases the risk of aspiration pneumonia. Choices B, C, and D are incorrect. High osmolarity formulas may cause diarrhea but do not directly increase the risk of aspiration. Sitting in a high-Fowler's position actually reduces the risk of aspiration by promoting proper digestion and reducing the chance of regurgitation. A residual of 65 mL 1 hour postprandial is within an acceptable range and does not directly indicate a risk for aspiration.

Correct Answer: A

Rationale: In the case of a patient experiencing acute chest pain, the initial response should include administering prescribed nitroglycerin. Nitroglycerin helps dilate blood vessels and improve blood flow to the heart, which can be beneficial in managing chest pain related to cardiac issues. Providing oxygen can also be helpful to support oxygenation. However, the priority in this scenario is to address the potential cardiac cause by administering nitroglycerin. Calling for emergency assistance is crucial if the patient's condition does not improve or deteriorates. Reassuring the patient is essential for emotional support but should not be the primary intervention in the case of acute chest pain.

Correct Answer: D

Rationale: A heart rate of 146/min is abnormal for a preschooler and indicates tachycardia, which should be reported to the provider. Choices A, B, and C fall within normal ranges for a preschooler's heart rate (80-120/min) and respiratory rate (22-34/min), so they do not require immediate reporting. Option D is the correct answer as it deviates significantly from the normal range and may indicate an underlying health issue that needs attention.

Correct Answer: C

Rationale: Cold extremities are a critical sign of impending death as they indicate decreased circulation, leading to poor perfusion to the extremities. This phenomenon occurs as the body redirects blood flow to vital organs, preparing for the end of life. Hypertension and tachycardia are less likely to be seen in the terminal phase and are usually associated with other conditions like shock or sepsis. Diaphoresis, or excessive sweating, may occur in various situations but is not a specific indicator of impending death in this context.

Correct Answer: B

Rationale: The correct answer is B because inhaling deeply and slowly elevates the cylinder on the spirometer, promoting lung expansion. Choice A is incorrect as exhaling deeply before inhaling is not the correct technique for using an incentive spirometer. Choice C is incorrect as inhaling quickly through the spirometer does not promote optimal lung expansion. Choice D is incorrect as inhaling several short breaths does not facilitate the proper use of an incentive spirometer.
