Health Promotion and Maintenance NCLEX PN Questions

1. The LPN is taking care of a 176-pound client who has recently been diagnosed with diabetes. The primary healthcare provider has written an order for Lantus� (insulin glargine injection) 100 units/mL, using weight-based dosing of 0.2 units/kg per day. The LPN should prepare ____ units for administration.

A. 12
B. 35
C. 16
D. 9

Correct answer: B

Rationale: To calculate the correct dosage, first convert the client's weight from pounds to kilograms. As 1 kg = 2.2 pounds, 176 pounds � 2.2 = 80 kg. The client should receive 0.2 units for every kilogram, which equals 16 units. Therefore, the total amount to prepare is 16 units x 100 units/mL = 1600 units. Considering the medication concentration of 100 units/mL, 1600 units � 100 units/mL = 16 mL. However, since the question asks for the number of units, the final answer is 16 units x 2 injections = 32 units. Therefore, the LPN should prepare 32 units for administration.

2. At what age are yearly mammograms recommended to start?

A. Yearly mammograms are recommended starting at age 25.
B. Yearly mammograms are recommended starting at age 40.
C. Yearly mammograms are not necessary unless there is a family history of breast cancer.
D. Yearly mammograms are recommended starting at age 20 and continuing until menopause begins.

Correct answer: B

Rationale: The correct answer is B. The American Cancer Society recommends yearly mammograms starting at age 40 and continuing for as long as a woman is in good health. Clinical breast examination should be done about every 3 years for women in their 20s and 30s and every year for women age 40 and older. Women should know how their breasts normally look and feel and report any breast change promptly to the healthcare provider. Breast self-examination should be done monthly starting when a woman is in her 20s. Choice A is incorrect as mammograms are not recommended to start at age 25. Choice C is incorrect as yearly mammograms are still recommended even without a family history of breast cancer. Choice D is incorrect as the recommended age for starting yearly mammograms is 40, not 20.

3. A nurse assisting with data collection plans to perform the Romberg test. After describing the test to the client, the nurse tells the client that it will help reveal which disorder?

A. Loss of hearing acuity
B. A problem with balance
C. A problem with distant hearing
D. A problem discriminating high-pitched and low-pitched sounds

Correct answer: B

Rationale: The Romberg test is a balance assessment that evaluates cerebellar function. During the test, the client stands with feet together and eyes closed, aiming to maintain balance for about 20 seconds. This test helps identify issues related to balance and proprioception, not hearing acuity or sound discrimination. Choices C and D are incorrect as the Romberg test focuses on balance, not distant hearing or sound discrimination.

4. 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.

5. When reviewing a client's medical notes to confirm pregnancy, a nurse should look for which finding to determine that pregnancy is confirmed?

A. Amenorrhea
B. Thinning of the cervix
C. Palpable fetal movement
D. Positive result on a home urine test for pregnancy

Correct answer: C

Rationale: To confirm pregnancy, the presence of palpable fetal movement is a positive indicator. Palpable fetal movement is a certain sign of pregnancy, known as a fetal movement felt by the examiner. Amenorrhea is a presumptive sign of pregnancy as it is reported by the woman but is not confirmatory. Thinning of the cervix (Hegar sign) is a probable sign of pregnancy, which is not confirmatory. A positive result on a home urine test for pregnancy is also a probable indicator. However, a positive pregnancy test result can sometimes yield false-positive results due to various factors like medication, recent pregnancy, or errors in reading.
