HESI Practice Test for Fundamentals

Correct Answer: D

Rationale: The correct answer is D. Turning a patient's head with a neck injury to the side when giving oral care can lead to harm or further injury. The neck should be kept in a neutral position to prevent exacerbation of the injury. Choices A, B, and C are not actions that require immediate nurse intervention. Not offering a backrub, not washing a patient's hair, or turning off the television are not critical issues that pose harm to the patient's well-being or safety.

Correct Answer: A

Rationale: The correct answer is A: 'Using a cuff that is too small will result in an inaccurately high reading.' When obtaining blood pressure for an obese client, it is crucial to use a larger cuff to ensure an accurate reading. Choice B is incorrect because using a cuff that is too large for an obese client would actually result in an inaccurately low reading. Choice C is incorrect as a regular size cuff is not appropriate for obese clients due to their larger arm circumference. Choice D is incorrect because using a cuff of any size as long as it fits is not suitable for obtaining accurate blood pressure readings on an obese client.

Correct Answer: A

Rationale: The correct answer is A: Chicken breast. In chronic kidney disease, a low-protein diet is often recommended to reduce the workload on the kidneys. Chicken breast is a high-protein food that should be limited in such diets to help manage the progression of kidney disease. Choices B, C, and D are low in protein and are generally suitable for individuals following a low-protein diet. Apples, rice, and bananas can be included in moderation as part of a balanced diet for individuals with chronic kidney disease.

Correct Answer: B

Rationale: To administer 200 mg of metoprolol using 100 mg tablets, the healthcare professional should give 2 tablets. Each tablet contains 100 mg of metoprolol, so 2 tablets will provide the required 200 mg dose. Choice A is incorrect because 1 tablet would only provide 100 mg, which is insufficient. Choice C is incorrect as fractions of tablets are usually not used in practice to ensure accurate dosing. Choice D is incorrect as it would result in an overdose, providing 400 mg instead of the prescribed 200 mg.

Correct Answer: B

Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.
