Health Promotion and Maintenance NCLEX RN Questions

1. Which of the following situations warrants a measurement for orthostatic hypotension?

A. A 36-year-old male with a spinal injury
B. An 86-year-old female with significantly altered mental status
C. A 58-year-old female with near-syncope
D. A 41-year-old male with acute deep vein thrombosis

Correct answer: C

Rationale: The correct answer is a 58-year-old female with near-syncope. Orthostatic hypotension is a drop in blood pressure of greater than 20 mmHg systolic when moving from a sitting or lying position to standing. Patients at higher risk include those with syncope or near-syncope, symptomatic hypovolemia, and those prone to falls. The other choices are less likely to present with orthostatic hypotension. A spinal injury, altered mental status, and acute deep vein thrombosis are not directly associated with the immediate need for orthostatic hypotension measurement.

2. A nonimmunized child appears at the clinic with a visible rash. Which of the following observations indicates the child may have rubeola (measles)?

A. Small blue-white spots are visible on the oral mucosa.
B. The rash begins on the trunk and spreads outward.
C. There is low-grade fever.
D. The lesions have a "teardrop-on-a-rose-petal"? appearance.

Correct answer: A

Rationale: The presence of small blue-white spots on the oral mucosa, known as Koplik's spots, is characteristic of measles (rubeola) infection. These spots typically appear on the buccal mucosa opposite the second molars, 1-2 days before the rash onset, and last until 2 days after the rash appears. While Koplik's spots are pathognomonic for measles, their absence does not rule out the diagnosis. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because the rash pattern, presence of low-grade fever, and characteristic appearance of lesions are not specific indicators of measles infection.

3. What is involved in obtaining informed consent?

A. An explanation of the reasons for the procedure
B. A signature on a form indicating the client agrees to the procedure
C. A statement affirming liability if complications arise during the procedure
D. Both A and C

Correct answer: A

Rationale: Informed consent involves providing the client with an explanation of the reasons for the procedure, the potential risks, benefits, and available alternatives. It is essential for the healthcare provider to ensure that the client understands the information provided before agreeing to the procedure. While obtaining a signature on a consent form is part of the process, it is not the sole indicator of informed consent. Option C, which mentions liability statements, is incorrect as informed consent focuses on ensuring the client understands the procedure, not on affirming liability. Therefore, the correct answer is the explanation of the reasons for the procedure.

4. While caring for a client in labor, a nurse attaches an electronic fetal monitor to the client's abdomen to assess the baby's heart rate. The nurse observes that the baby's heart rate slows down during each contraction and does not return to normal limits until after the contraction is complete. What type of fetal heart rate change does this pattern describe?

A. Variable decelerations
B. Late decelerations
C. Early decelerations
D. Accelerations

Correct answer: B

Rationale: Late decelerations are characterized by the baby's heart rate declining in utero during contractions. The heart rate drops below baseline and stays low until after the contraction ends. Late decelerations are concerning as they indicate uteroplacental insufficiency, which can compromise fetal oxygenation. This pattern is a non-reassuring sign and requires immediate intervention. Variable decelerations are typically abrupt decreases in heart rate, often associated with cord compression. Early decelerations, on the other hand, mirror the contractions and are considered benign, resulting from fetal head compression. Accelerations are reassuring signs of fetal well-being, indicating a responsive and healthy fetal nervous system.

5. Sinusitis is caused by:

A. Bacteria
B. Fungus
C. Virus
D. Any of the above

Correct answer: D

Rationale: Sinusitis can be caused by bacteria, viruses, or fungi. While bacterial infections are the most common cause, viral or fungal infections can also lead to sinusitis. Therefore, the correct answer is 'Any of the above.' Choices A, B, and C are incorrect because they only represent individual causes of sinusitis, whereas choice D encompasses all possible causes.
