Health Promotion and Maintenance NCLEX PN Questions

1. A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?

A. Tests the right eye, then tests the left eye, and finally tests both eyes together
B. Assesses both eyes together, then assesses the right and left eyes separately
C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision

Correct answer: A

Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.

2. What classification of drug is Diltiazem?

A. Calcium-Channel Blocker
B. NSAID
C. ACE Inhibitor
D. Beta-Blocker

Correct answer: A

Rationale: Diltiazem belongs to the class of calcium-channel blockers, not NSAIDs, ACE Inhibitors, or Beta-Blockers. Calcium-channel blockers like Diltiazem are used to treat conditions such as hypertension by relaxing blood vessels and increasing the supply of blood and oxygen to the heart. Therefore, the correct classification for Diltiazem is a Calcium-Channel Blocker. NSAIDs, ACE Inhibitors, and Beta-Blockers belong to different classes of drugs with distinct mechanisms of action and therapeutic uses, making them incorrect choices for Diltiazem.

3. A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?

A. The fingers curl tightly, and the toes curl forward.
B. The toes flare, and the big toe is dorsiflexed.
C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
D. The infant turns to the side that is touched.

Correct answer: B

Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.

4. Which of the following statements, if made by the parents of a newborn, does not indicate a need for further teaching about cord care?

A. "I should not put alcohol on my baby's cord 3-4 times a day."?
B. "I should not put the baby's diaper on so that it covers the cord."?
C. "I should call the physician if the cord becomes dark."?
D. "I should wash my hands before and after I take care of the cord."?

Correct answer: B

Rationale: Parents should be taught not to cover the cord with a diaper to allow for air exposure and drying, preventing infection. The statement 'I should put alcohol on my baby's cord 3-4 times a day' indicates a need for further teaching as current recommendations do not include using alcohol on the cord, which can interfere with natural healing. While it is normal for the cord to turn dark as it dries, so the statement 'I should call the physician if the cord becomes dark' is accurate, it is not the best answer for this question. Washing hands before and after caring for the cord is important to prevent the transfer of pathogens, so this statement does not require further teaching.

5. What is the primary focus of a case manager?

A. Addressing nursing care needs at discharge.
B. Managing the comprehensive care needs of the client for continuity of care.
C. Providing client education needs upon discharge.
D. Securing financial resources for needed care.

Correct answer: B

Rationale: The correct answer is 'Managing the comprehensive care needs of the client for continuity of care.' Case managers oversee all aspects of a client's care to ensure continuity throughout their healthcare journey. Choice A is incorrect as it focuses only on nursing care needs at discharge, which is just a part of the overall care needed. Choice C narrows down the focus to client education needs, excluding other essential care components. Choice D solely considers financial resources, neglecting the broader scope of care needs that a case manager is accountable for.
