HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: The correct answer is A because cleaning the outside part of hearing aids with a damp cloth is an appropriate method. Rubbing alcohol can damage ear molds, so choice B is incorrect. Keeping the volume of hearing aids turned up high may lead to discomfort, making choice C incorrect. Removing batteries when not in use at night is good practice for battery life, but it does not directly relate to understanding cleaning instructions, so choice D is less relevant in this context.

Correct Answer: A

Rationale: Having the client demonstrate the procedure is the most appropriate action to evaluate understanding within the psychomotor domain of learning. This allows the instructor to assess the client's ability to perform the skill, which is a key aspect of this domain. Choice B, explaining the procedure again, focuses on the cognitive domain rather than the psychomotor domain. Choice C, asking the client to describe the procedure, pertains more to the verbal or cognitive domain of learning. Choice D, observing the client watching a video on the procedure, does not directly assess the client's ability to perform the skill in the psychomotor domain.

Correct Answer: A

Rationale: The correct action for the nurse to take is to remove the basin of water from the client's bed immediately. Soaking a client's foot in a basin of water placed on the bed can lead to spills, create infection risks, and is not a safe practice. It is essential to prioritize the safety and well-being of the client by ensuring a safe environment during care procedures. Choices B, C, and D are incorrect as they do not address the immediate risk associated with the situation. Reminding the UAP to dry between the client's toes, advising about potential skin damage, or adding skin cream do not mitigate the immediate hazards of having a basin of water on the bed.

Correct Answer: A

Rationale: Abdominal cramping is a common manifestation of hyponatremia (low sodium levels). When sodium levels drop, it can lead to changes in the body's water balance, affecting cell function and causing symptoms like abdominal cramping. Increased thirst (choice B) is more commonly associated with hypernatremia (high sodium levels) due to the body's attempt to dilute the excess sodium. Elevated blood pressure (choice C) and elevated heart rate (choice D) are not typically direct manifestations of low sodium levels and are more commonly seen in conditions like dehydration or shock.

Correct Answer: D

Rationale: The correct answer is 'Upper arm circumference.' Upper arm circumference is a better indicator of total muscle mass in adolescents compared to height, weight, or triceps skinfold thickness. Triceps skinfold thickness primarily reflects subcutaneous fat, while weight and height are not specific to muscle mass. Upper arm circumference directly measures the muscle mass in the upper arm and can provide a more accurate assessment in this context. Therefore, choices A, B, and C are incorrect because they do not directly reflect total muscle mass in adolescents.
