Exam Cram NCLEX RN Practice Questions

1. A 1-month-old infant has a head measurement of 34 cm and a chest circumference of 32 cm. Based on the interpretation of these findings, what action would the nurse take?

A. Refer the infant to a physician for further evaluation.
B. Consider these findings normal for a 1-month-old infant.
C. Expect the chest circumference to be greater than the head circumference.
D. Ask the parent to return in 2 weeks to re-evaluate the head and chest circumferences.

Correct answer: B

Rationale: In infants, a normal head measurement is approximately 32 to 38 cm, and it is usually around 2 cm larger than the chest circumference. These measurements vary with age; between 6 months and 2 years, both measurements are approximately the same, and after age 2 years, the chest circumference becomes greater than the head circumference. Given that the 1-month-old infant's head measurement is within the typical range and slightly larger than the chest circumference, the nurse should consider these findings normal. There is no indication to refer the infant for further evaluation or to have the parent return for re-evaluation in 2 weeks, as these measurements fall within the expected parameters for a 1-month-old infant.

2. An 86-year-old client with decreased visual acuity who uses a cane for mobility requires fall prevention education. What should the nurse teach this client to reduce the risk of falling at home?

A. Take off shoes while in the house and wear only socks
B. Limit activities to the lower level of the home
C. Keep a lamp near the door of every room
D. Install non-slip pads in the shower or bathtub

Correct answer: D

Rationale: To reduce the risk of falling at home for an elderly client with decreased visual acuity and using a cane for mobility, installing non-slip pads in the shower or bathtub is crucial. This measure helps prevent slips and falls in areas where water accumulation may occur. While taking off shoes and wearing socks may seem comfortable, it increases the risk of slipping. Limiting activities to the lower level of the home may restrict the client's independence and quality of life unnecessarily. Keeping a lamp near the door of every room may improve visibility but does not directly address the risk of falls associated with mobility and visual acuity issues.

3. You are taking care of a patient who has active TB. The patient has been put on airborne precautions and is in a special room. You must wear a HEPA mask when you enter the room. Now, the patient has to leave the room and go to the radiology department. How can you transport this patient to the radiology department without spreading TB throughout the hospital?

A. Have everyone along the route to the radiology department wear a HEPA mask.
B. Have patients along the route to the radiology department wear a HEPA mask.
C. Have staff along the route to the radiology department wear a HEPA mask.
D. Place a HEPA mask on the patient.

Correct answer: D

Rationale: To prevent the spread of TB throughout the hospital, it is essential to place a HEPA mask on the patient before transporting them to the radiology department. Expecting everyone along the route to wear a HEPA mask is not practical due to the high cost and the need for special fittings. Having patients or staff wear HEPA masks along the route is also not feasible and may not effectively contain the spread of TB.

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. The abbreviation pc is defined as ________________.

A. before the meal
B. with the meal
C. after the meal
D. post corpi

Correct answer: C

Rationale: The correct answer is C: 'after the meal.' In medical terminology, 'pc' is an abbreviation for 'post cibum,' which means 'after eating' or 'after the meal.' This term is used to indicate when a medication should be taken concerning meals. Choices A, B, and D are incorrect. 'Before the meal' (A) is typically abbreviated as 'ac,' 'with the meal' (B) is abbreviated as 'pc,' and 'post corpi' (D) is not a valid medical abbreviation or term.
