Nursing Elites

1. In conducting a health screening for 12-month-old children, the nurse expects them to have been immunized against which of the following diseases?

• A. measles, polio, pertussis, hepatitis B
• B. diphtheria, pertussis, polio, tetanus
• C. rubella, polio, pertussis, hepatitis A
• D. measles, mumps, rubella, polio

Correct answer: B

Rationale: By 12 months of age, children should have received vaccines for diphtheria, pertussis, polio, and tetanus (DTaP and IPV). The correct answer is B as it includes these vaccines that are typically administered in the first year of life. Measles, mumps, and rubella (MMR) vaccination usually begins at 12 months of age but is not expected to be completed by this time. Choices A and C are incorrect as they include diseases that are not part of the routine immunization schedule for a 12-month-old child.

2. A nurse is interviewing an older adult while assisting with data collection. Which client comment regarding vision requires immediate discussion with the health care provider?

• A. "If I go from a very bright room to a very dark room, I have some trouble adjusting."
• B. "I have to hold my newspaper farther and farther away from me when I read."
• C. "I have a little trouble telling if my same-colored shirts and blouses actually match; the colors seem the same to me."
• D. "It looks like I have a blank spot in the middle of what I'm trying to see."

Correct answer: D

Rationale: The correct answer is "It looks like I have a blank spot in the middle of what I'm trying to see." Seeing blank spots in the middle of an object is a sign of central vision loss, which is a symptom of macular degeneration. Macular degeneration is a serious condition that requires immediate discussion with a healthcare provider to prevent further vision loss. Choice A, mentioning difficulty adjusting between bright and dark rooms, is a common issue related to changes in lighting and not a cause for immediate concern. Choice B, having to hold objects farther away when reading, is indicative of presbyopia, a normal age-related change in vision. Choice C, experiencing slight changes in color perception, is also a common age-related change and not an urgent issue that necessitates immediate discussion with a healthcare provider.

3. When a client wishes to improve her appearance by removing excess skin from her face and neck, the nurse should provide teaching regarding which of the following procedures?

• A. dermabrasion
• B. rhinoplasty
• C. blepharoplasty
• D. rhytidectomy

Correct answer: D

Rationale: The correct answer is 'rhytidectomy.' Rhytidectomy, commonly known as a face-lift, is the procedure for removing excess skin from the face and neck. Dermabrasion involves spraying a chemical to freeze the skin lightly, followed by abrasion with sandpaper or a revolving wire brush, used for removing scars, severe acne, and tattoo pigment. Rhinoplasty is for improving the nose's appearance by reshaping the nasal skeleton and overlying skin. Blepharoplasty removes loose and protruding fat from the upper and lower eyelids. Therefore, when a client wants to address excess skin in the face and neck, rhytidectomy is the appropriate procedure.

4. While performing a physical assessment on a 6-month-old infant, the nurse observes head lag. Which of the following nursing actions should the nurse perform first?

• A. Ask the parents to allow the infant to lie on his stomach to promote muscle development.
• B. Notify the physician because a developmental or neurological evaluation is indicated.
• C. Document the findings as abnormal in the nurse's notes.
• D. Explain to the parents that their child is likely to have developmental delays.

Correct answer: B

Rationale: Head lag should be completely resolved by 4 months of age. Continuing head lag at 6 months of age indicates the need for further developmental or neurological evaluation. Laying the infant on his stomach promotes muscle development of the neck and shoulder muscles, but because of the age of this child, a referral should be the first action. The findings are abnormal for a 6-month-old infant. Significant head lag can be seen in infants with Down syndrome and hypoxia, as well as neurological and other metabolic disorders. While some of these disorders might include developmental delays, stating this to the parents without a proper evaluation can cause unnecessary distress. The priority is to identify the cause of the head lag through a medical evaluation before discussing potential outcomes with the parents.

5. 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.
