Health Promotion and Maintenance NCLEX PN Questions

1. 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.

2. A client has just returned from surgery where a femoral-popliteal bypass was performed. The nurse has assessed the client and is unable to feel a pulse at either the dorsalis pedis or the posterior tibial sites of the left foot. The foot feels warm, and the color is pink. What action should the nurse perform next to prevent ischemia?

A. Notify the physician immediately
B. Obtain a Doppler device to check for pulses, and notify the physician if they are still absent
C. Wait 30 minutes and recheck the pulses
D. Document the finding

Correct answer: B

Rationale: The nurse should immediately obtain a Doppler device and recheck the pulses. The dorsalis pedis and posterior tibial pulses can be difficult to assess and might need to be verified with a Doppler device. Since the client just had surgery with a risk of arterial insufficiency, close monitoring is crucial. If pulses are not palpable, it indicates an emergent situation requiring immediate physician notification. Waiting 30 minutes before reassessment could lead to foot ischemia. While documenting findings is essential, it should follow pulse confirmation or necessary interventions to ensure the client's foot viability.

3. A hepatitis B screen is performed on a pregnant client, and the results indicate the presence of antigens in the client's blood. On the basis of this finding, the nurse makes which determination?

A. Hepatitis immune globulin and vaccine will be administered to the newborn infant soon after birth
B. The results are negative.
C. The results indicate that the mother does not have hepatitis B
D. The client needs to receive the hepatitis B series of vaccines.

Correct answer: A

Rationale: A hepatitis B screen is performed to identify antigens in maternal blood. If antigens are present, it indicates that the mother is a carrier, and the newborn will need to receive hepatitis immune globulin and vaccine soon after birth to prevent transmission. Therefore, choice A is correct. Choices B and C are incorrect because the presence of antigens indicates a positive result, not a negative one or the absence of hepatitis B in the mother. Choice D is incorrect as it suggests the client needs to receive the hepatitis B series of vaccines, which is not the immediate action required when antigens are found in the maternal blood.

4. When obtaining a health history on a menopausal woman, which information should a nurse recognize as a contraindication for hormone replacement therapy?

A. family history of stroke
B. ovaries removed before age 45
C. frequent hot flashes and/or night sweats
D. unexplained vaginal bleeding

Correct answer: D

Rationale: When considering hormone replacement therapy for a menopausal woman, unexplained vaginal bleeding should be recognized as a contraindication. This is because it could be indicative of a serious underlying condition that needs investigation before initiating hormone therapy. A family history of stroke, by itself, is not a contraindication for hormone replacement therapy, unless the woman herself has a history of stroke or blood-clotting events. Ovaries removed before age 45 may actually increase the likelihood of needing hormone replacement therapy due to early menopause. Frequent hot flashes and night sweats, on the other hand, are symptoms that can be relieved by hormone replacement therapy, making them a potential indication rather than a contraindication.

5. During a health assessment, a nurse is assisting with gathering subjective data from a client and plans to ask the client about the medical history of the client's extended family. About which family members would the nurse ask the client?

A. Aunts, uncles, grandparents, and cousins
B. Foster children and their parents
C. Wife's children from a previous marriage
D. Wife and wife's parents

Correct answer: B

Rationale: The correct answer is 'Aunts, uncles, grandparents, and cousins.' When gathering medical history from the client's extended family, it is essential to inquire about relatives beyond the nuclear family, such as aunts, uncles, grandparents, and cousins, as they share genetic and environmental influences. Choice C, 'Wife's children from a previous marriage,' pertains to stepchildren, not extended family members. Choice B, 'Foster children and their parents,' involves individuals who are not biologically related to the client's family. Choice D, 'Wife and wife's parents,' focuses solely on immediate family members and excludes the client's extended family members, which are crucial for a comprehensive health assessment.
