NCLEX RN Predictor Exam

1. When are manual hematocrits done?

A. to monitor anemia
B. by using a microhematocrit tube.
C. to measure the percentage of plasma to cells.
D. All of the above.

Correct answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

2. When caring for children with a different cultural perspective, what challenge may the nurse recognize?

A. Children have spiritual needs that are influenced by their stages of development
B. Children have spiritual needs that are direct reflections of what is occurring in their homes
C. Religious beliefs rarely affect the parents' perceptions of the illness
D. Parents are often the decision-makers, and they have no knowledge of their children's spiritual needs

Correct answer: A

Rationale: When caring for children with different cultural perspectives, nurses should acknowledge that children have spiritual needs that are influenced by their stages of development. This understanding is crucial as children, like adults, have varying spiritual needs based on their age and the religious environment within their family. Recognizing and addressing these spiritual needs is essential for providing holistic care. Choices B, C, and D are incorrect as they do not accurately reflect the influence of children's developmental stages on their spiritual needs and the importance of considering these needs in their care.

3. The hospital has sounded the call for a disaster drill on the evening shift. Which of these clients would the nurse prioritize first on the list to be discharged in order to make a room available for a new admission?

A. A middle-aged client with a history of being ventilator dependent for over seven (7) years and admitted with bacterial pneumonia five days ago.
B. A young adult with diabetes mellitus Type 2 for over ten (10) years and admitted with antibiotic-induced diarrhea 24 hours ago.
C. An elderly client with a history of hypertension, hypercholesterolemia, and lupus, and was admitted with Stevens-Johnson syndrome that morning.
D. An adolescent with a positive HIV test and admitted for acute cellulitis of the lower leg 48 hours ago.

Correct answer: A

Rationale: The best candidate for discharge during a need for emergency room availability is a stable patient with a chronic condition who is familiar with their care. In this scenario, the middle-aged client in option A, who has been ventilator dependent for over seven years and admitted with bacterial pneumonia five days ago, is most suitable for discharge. This client is likely stable and can continue medication therapy at home, making them the most appropriate choice for discharge at this time. Choice B should not be the priority for discharge as the young adult with diabetes mellitus Type 2 admitted with antibiotic-induced diarrhea 24 hours ago may need further monitoring and management of their condition. Choice C, the elderly client with multiple comorbidities and admitted with Stevens-Johnson syndrome on the same day, is not a suitable candidate for immediate discharge as they may require ongoing medical attention and observation. Choice D, the adolescent with a positive HIV test and admitted for acute cellulitis of the lower leg 48 hours ago, should not be discharged first as acute cellulitis may require continued treatment and monitoring, especially in the context of a positive HIV status.

4. A urine pregnancy test:

A. May be negative even if a blood pregnancy test is positive.
B. Is positive only during the first trimester of pregnancy.
C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
D. All of the above.

Correct answer: A

Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.

5. Mr. and Mrs. K have just adopted a newborn infant and are preparing to take him home from the hospital for the first time. Which safety measure is most appropriate for the clients in this situation?

A. Turn the handles of pans on the stove inward
B. Set up a baby gate at the top of the stairs
C. Cover electrical outlets with child-proof plugs
D. Install an approved car seat that is facing backward in the back seat

Correct answer: D

Rationale: Parents of newborn infants should use an approved car seat that has been installed facing backward in the back seat of the car. Securing infants in car seats, even from the first ride home from the hospital, promotes safety while transporting. While safety measures at home such as baby gates or outlet covers are important, they are not the priority safety measures until the baby is old enough to be mobile. The car seat is crucial for protecting the newborn during transportation, ensuring proper positioning and restraint in the event of sudden stops or accidents. Turning handles of pans on the stove inward, setting up a baby gate, and covering electrical outlets are important safety measures at home but are not as critical for the immediate safety of a newborn during transportation.
