A nurse is preparing to test cranial nerve I. Which item does the nurse obtain to test this nerve?
- A. Coffee
- B. A tuning fork
- C. A wisp of cotton
- D. An ophthalmoscope
Correct Answer: C
Rationale: To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint. Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I. Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve). Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.

The LPN is caring for a client newly diagnosed with HIV. Which statement made by the client regarding antiretroviral therapy (ART) would require correction from the nurse?
- A. "If I start ART and use condoms, I'm less likely to transmit HIV to my partner."?
- B. "I can still use ART even though I am Hepatitis C positive."?
- C. "I will need to be on ART indefinitely."?
- D. "I know I will need to come back for blood draws so that I can begin ART when my CD4 count is over 1,000 cells/mm3."?
Correct Answer: D
Rationale: The correct answer is the statement, "I know I will need to come back for blood draws so that I can begin ART when my CD4 count is over 1,000 cells/mm3."? This statement would require correction from the nurse because initiating ART when the CD4 count is over 1,000 cells/mm3 is not supported by guidelines. The World Health Organization (WHO) recommends making treatment a priority for those with a CD4 count of ≤350 cells/mm3, as early intervention can help delay disease progression. Therefore, waiting for a CD4 count of over 1,000 cells/mm3 is not in line with current recommendations.
Choice A is correct, as studies have shown that using condoms along with ART can significantly reduce the risk of HIV transmission to sexual partners. Choice B is also correct because being Hepatitis C positive does not contraindicate the use of ART. Choice C is correct as well, as ART is typically needed indefinitely to maintain viral suppression and manage HIV. Therefore, the only statement that would require correction is Choice D.
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.
The nurse is caring for a female client who has recently been diagnosed with cancer and will soon begin chemotherapy. Which of these statements would require additional follow-up and education?
- A. I will be most susceptible to an infection between 7 and 12 days after chemotherapy.
- B. I should try to get my annual teeth cleaning in before beginning chemotherapy.
- C. I should wait until all my hair falls out to purchase a wig.
- D. I should try to drink 8-10 glasses of water a day.
Correct Answer: C
Rationale: This client is at risk for altered body image due to chemotherapy-induced hair loss. A wig can assist in coping with this change. It is advisable for the client to shop for a wig before hair loss occurs to better match color and style. Waiting until all hair falls out may lead to stress and limited options in finding a suitable wig. Choices A, B, and D are accurate. Understanding the timing of susceptibility to infection, maintaining oral health before chemotherapy, and staying hydrated are important aspects of care during chemotherapy. Therefore, the statement 'I should wait until all my hair falls out to purchase a wig' requires additional follow-up and education.
Light therapy can be effective for:
- A. overcoming weight problems.
- B. helping with allergies.

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders.
A healthcare professional reviewing a client's health care record notes documentation that the client has Heberden nodes of the distal interphalangeal joints. Which disorder does the healthcare professional determine that the client has?
- A. Scoliosis
- B. Osteoarthritis
- C. Rotator cuff lesions
- D. Carpal tunnel syndrome
Correct Answer: B
Rationale: The correct answer is Osteoarthritis. Osteoarthritis is characterized by hard, nontender nodules of 2 to 3 mm or larger. These osteophytes (bony overgrowths) of the distal interphalangeal joints are called Heberden nodes. In this disorder, when these nodes occur on the proximal interphalangeal joints, they are called Bouchard nodes. Heberden nodes are not associated with scoliosis, rotator cuff lesions, or carpal tunnel syndrome. Therefore, choices A, C, and D are incorrect.
