Correct Answer: C

Rationale: The correct answer is C: Coffee. Coffee should be avoided by clients with GERD as it can relax the lower esophageal sphincter, leading to an increase in GERD symptoms. Choices A, B, and D are not directly associated with worsening GERD symptoms and can be included in moderation in the diet of a client with GERD.

Correct Answer: C

Rationale: To completely remove ointment, especially zinc oxide, mineral oil should be used. Mineral oil helps in gently breaking down and lifting the ointment without causing irritation. Mild soap and water (Choice A) may not be effective in completely removing zinc oxide. A cotton ball (Choice B) may not provide the necessary lubrication to aid in the removal process. Alcohol swabs (Choice D) can be harsh on the skin and are not recommended for this purpose.

Correct Answer: C

Rationale: Discussing approaches to chronic pain control is the most appropriate action in this situation as it helps the client manage the chronic pain associated with Heberden's nodes. Reviewing the client's dietary intake of high protein foods (Choice A) is not directly related to managing the pain caused by Heberden's nodes. Notifying the healthcare provider immediately (Choice B) may not be necessary unless there are urgent complications. Assessing the client's radial pulses and capillary refill time (Choice D) is important but not the priority in addressing the client's reported pain and the presence of Heberden's nodes.

Correct Answer: C

Rationale: A child with an IQ of 45 is classified as 'Trainable' in the context of cognitive impairment levels. This category is determined by an IQ range of 35 to 55. Choice A ('Within the normal low range') is incorrect as an IQ of 45 falls within the range associated with the 'Trainable' level, not the 'Normal low range.' Choice B ('Educable') is incorrect because this classification typically corresponds to individuals with slightly higher IQs that allow for academic progress with support. Choice D ('Severe') is incorrect as it does not align with the IQ level of 45, which falls within the 'Trainable' category.

Correct Answer: C

Rationale: To infuse 150 mL over 90 minutes, the pump should be set to 100 ml/hour (150 mL / 1.5 hours). This rate ensures that the medication is delivered at the proper rate as prescribed. Choices A, B, and D are incorrect because they do not reflect the correct calculation based on the volume of the IV bag and the infusion duration provided in the question.
