Practice HESI Fundamentals Exam

Correct Answer: C

Rationale: The correct way to use a cane is to hold it on the stronger side of the body. This helps to provide support and maintain alignment. Option A is incorrect because the cane should be held on the stronger side, not the weaker side. Option B is incorrect as the top of the cane should be at the level of the greater trochanter, not the waist. Option D is incorrect because the client should move the weaker limb forward with the cane for stability.

Correct Answer: A

Rationale: When a debilitated patient resists oral hygiene, the nurse should prioritize safety. Inserting an oral airway helps keep the mouth open, ensuring adequate access for oral care procedures while preventing any accidental biting or closure of the airway. Placing the patient in a flat, supine position may not address the resistance issue and can lead to aspiration risk. Using undiluted hydrogen peroxide is not recommended due to its potential harmful effects on oral tissues. Proceeding quickly without communication can escalate the situation and compromise patient-centered care.

Correct Answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.

Correct Answer: B

Rationale: The correct dosing schedule for the client to follow is to take the medication at 8 a.m., 4 p.m., and midnight. This timing spaces the doses evenly over the waking hours, ensuring consistent therapeutic levels of the medication. Choice A (9 a.m., 1 p.m., and 5 p.m.) does not evenly distribute the doses throughout the day. Choices C (Before breakfast, before lunch, and before dinner) and D (With breakfast, with lunch, and with dinner) do not provide the required frequency of dosing needed for optimal therapeutic effect.

Correct Answer: B

Rationale: The correct first action when performing a physical assessment on a toddler is to use minimal physical contact. This approach helps the toddler become comfortable and reduces anxiety during the assessment. Traumatic procedures (Choice A) should never be the first action as they can cause distress. Proceeding from head to toe (Choice C) is a common sequence in physical assessments but does not address the initial need to establish trust and comfort. Explaining the exam in detail (Choice D) is important but should come after establishing a rapport through minimal physical contact.
