Nursing Elites

1. What causes an older female client's hair to turn gray?

• A. ''A loss of melanin occurs in the normal aging process.''
• B. ''The number of sweat glands and blood vessels decreases in the normal aging process.''
• C. ''The skin on the scalp becomes thin, causing moisture to escape.''
• D. ''It is caused by hereditary factors.''

Correct answer: A

Rationale: The correct answer is 'A loss of melanin occurs in the normal aging process.' Graying hair in older adults is primarily due to a decrease in the number of melanocytes responsible for providing pigment and hair color. This reduction in melanin production leads to gray hair. The other choices are incorrect. While it is true that the skin becomes thinner with aging and the number of sweat glands and blood vessels decreases, these changes are not directly related to graying hair. Additionally, hereditary factors can influence when graying starts, but they do not cause the graying of hair itself.

2. Which of the following vaccines is not part of the regular schedule of immunizations for children?

• A. DTaP
• B. MMR
• C. Hib
• D. hepatitis A

Correct answer: D

Rationale: The correct answer is hepatitis A. DTaP, MMR, and Hib are all part of the regular schedule of immunizations for children to protect them against diseases like diphtheria, tetanus, pertussis, measles, mumps, rubella, and Haemophilus influenzae type b. Hepatitis A vaccine is not included in the routine childhood immunization schedule but may be recommended in certain situations or regions where the disease is more prevalent. Hepatitis A is generally considered an optional vaccine for children but can be administered based on specific risk factors or regional guidelines.

3. The nurse is assessing an 18-month-old. Which of these statements made by the parent or caregiver would require follow-up?

• A. I'm worried that my child is not using two-word phrases yet.
• B. My child has recently taken a few steps but does not seem stable when standing.
• C. My child seems to have developed separation anxiety when I leave.
• D. I'm letting my child use a spoon to eat.

Correct answer: B

Rationale: The correct answer is 'My child has recently taken a few steps but does not seem stable when standing.' By 18 months of age, children should have taken their first steps and stand well. If a child hasn't made progress by this age, a physical therapy evaluation may be necessary. It is normal for an 18-month-old to start using a spoon to eat. However, the use of two-word phrases is not typically expected until 2 years of age. Separation anxiety is a common developmental phase that typically occurs between 6 and 18 months, so it does not require immediate follow-up. Therefore, the statement about the child not being stable when standing raises a red flag and necessitates further evaluation.

4. When caring for a patient who is hard-of-hearing, which of the following steps may be appropriate when communicating with the patient?

• A. Divide the verbal communication into smaller sections and address one at a time.
• B. Communicate only with written information.
• C. Ask multiple questions in a row quickly to make sure the patient is remaining engaged.
• D. Frequently communicate without assistive devices to help the patient improve their hearing.

Correct answer: A

Rationale: When caring for a patient who is hard-of-hearing, it is important to divide verbal communication into smaller sections and address them one at a time. This approach helps the patient follow along more easily and understand the information being conveyed. While using written information can also be beneficial, solely relying on written communication may not always be practical or feasible for effective interaction. Asking multiple questions quickly can overwhelm the patient and hinder their ability to process each question adequately. It is essential to give the patient sufficient time to comprehend and respond. Additionally, frequently communicating without assistive devices is not recommended. Using assistive devices can significantly enhance the patient's ability to hear and understand, promoting better communication and patient care.

5. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

• A. 0.9% sodium chloride
• B. 5% dextrose in water solution
• C. Sterile water
• D. Heparin sodium

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, heparin sodium, is an anticoagulant and is not used for flushing IV devices before and after blood administration.
