HESI Practice Test for Fundamentals

Correct Answer: C

Rationale: The rationale behind checking for impaired skin integrity in an immobile patient is that pressure reduces circulation to the affected tissue. Prolonged pressure on specific body parts can lead to reduced blood flow to those areas, causing tissue damage and potentially leading to pressure ulcers. Choices A, B, and D are incorrect because inadequate blood flow causing decreased tissue ischemia, limited caloric intake leading to thicker skin, and decreased verbalization of skin care needs are not directly related to the rationale for checking for impaired skin integrity in immobile patients.

Correct Answer: C

Rationale: The correct answer is C, 'Decreased potassium.' Clients with bulimia often have decreased potassium levels due to frequent vomiting, which causes a loss of this essential electrolyte. This loss can lead to various complications such as cardiac arrhythmias. Option A, 'Increased serum glucose,' is not typically associated with bulimia. Option B, 'Decreased albumin,' is more related to malnutrition or liver disease rather than bulimia. Option D, 'Increased sodium retention,' is not a common finding in clients with bulimia; instead, they may experience electrolyte imbalances like hyponatremia due to purging behaviors.

Correct Answer: A

Rationale: The correct answer is A: 'I will place the client in a private room.' Placing the client in a private room helps prevent the spread of MRSA, a contact precaution. Choice B is incorrect because visitors should be following standard precautions for MRSA, not just wearing a mask within a specific distance. Choice C is incorrect as the gown should be removed before exiting the client's room to prevent the spread of MRSA. Choice D is incorrect as an N95 respirator mask is not typically required for the care of a client with MRSA; standard precautions are usually sufficient.

Correct Answer: C

Rationale: The correct answer is C. Skipping meals to lose weight may indicate an eating disorder or significant distress, which can have serious health implications. This behavior raises concerns about the adolescent's physical and mental well-being. The nurse should prioritize addressing potential eating disorders and body image issues in this situation. Choices A, B, and D, while important, do not pose an immediate risk to the adolescent's health or well-being compared to the potential consequences of disordered eating behavior.

Correct Answer: B

Rationale: Teaching about a healthy diet is considered a primary prevention activity. Primary prevention aims to prevent the onset of a disease or health problem. Educating individuals on healthy lifestyle choices, such as diet modification, falls under primary prevention. Providing cholesterol screening (choice A) is a secondary prevention measure aimed at early detection. Offering information about antihypertensive medications (choice C) falls under secondary prevention, focusing on controlling risk factors. Developing a list of cardiac rehabilitation programs (choice D) is part of tertiary prevention, focusing on rehabilitation and improving outcomes post-disease onset.
