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. The nurse receives an order to administer phenytoin through the client's J-tube. The order instructs that tube feedings are stopped at least an hour prior to administering the medication and an hour after the medication is administered. Which of the following considerations may be a reason to discuss this order with the physician?

• A. The client has a history of Type II diabetes.
• B. The client is on a continuous tube-feeding regimen.
• C. The client is on fluid restriction.
• D. The pharmacy has provided phenytoin in tablet form.

Correct answer: B

Rationale: For a client on a continuous tube-feeding regimen, stopping tube feedings for two hours to administer this medication may compromise the client's nutritional status. This interruption can lead to inadequate nutrient intake, affecting the client's overall nutritional well-being. The other choices are less relevant in this situation. Type II diabetes does not directly impact the administration of phenytoin through a J-tube. Fluid restriction would not prevent the temporary interruption of tube feedings for medication administration. The form of phenytoin provided by the pharmacy does not impact the need to discuss the order with the physician regarding the client's continuous tube-feeding regimen.

3. While assessing a client’s skin, the nurse notes the presence of several large red-blue and purple areas on the client’s body that do not blanch when pressure is applied. The nurse documents this finding using which term?

• A. Psoriasis
• B. Anasarca
• C. Petechiae
• D. Ecchymosis

Correct answer: D

Rationale: Ecchymosis refers to a large patch of capillary bleeding into the tissues, commonly known as a bruise. The color of such an area changes from red-blue or purple to green, yellow, and brown before the area disappears. Pressure on the area will not cause it to blanch. Psoriasis is characterized by scaly erythematous patches with silvery scales on top, usually found on specific areas like the scalp, elbows, knees, low back, and anogenital area. Anasarca is bilateral or generalized edema, indicating a central problem like congestive heart failure or kidney failure. Petechiae are tiny purple or red spots resulting from tiny hemorrhages within the dermal and subdermal areas. Therefore, in this case, the correct term to document the described finding is Ecchymosis.

4. A nurse is preparing to listen to the apical heart rate in the area of the mitral valve in an adult client. The nurse should place the stethoscope on which part of the client's chest?

• A. Second left interspace
• B. Second right interspace
• C. Left lower sternal border
• D. Fifth left interspace at the midclavicular line

Correct answer: D

Rationale: The correct placement for auscultating the apical heart rate in the area of the mitral valve is the fifth left interspace at the midclavicular line. Placing the stethoscope in the second left interspace would be to listen to the pulmonic valve, the second right interspace is for the aortic valve, and the left lower sternal border is for the tricuspid valve.

5. While assisting with data collection, the nurse asks the client to close their jaws tightly. Subsequently, the nurse tries to open the closed jaws. In this technique, the nurse is assessing the motor function of which nerve?

• A. Trochlear nerve
• B. Abducens nerve
• C. Trigeminal nerve
• D. Oculomotor nerve

Correct answer: C

Rationale: The correct answer is C: Trigeminal nerve. To test the motor function of the trigeminal nerve (cranial nerve V), the nurse assesses the muscles of mastication by asking the client to clench their teeth. By trying to separate the client's jaws, the nurse evaluates the strength of the temporal and masseter muscles innervated by the trigeminal nerve. This technique helps assess if the trigeminal nerve is functioning properly. Choices A, B, and D are incorrect because they relate to other cranial nerves that are not involved in the specific motor function being tested in this scenario. These nerves are usually assessed through different examinations such as assessing the pupils and extraocular movements, which are not part of the jaw clenching and opening technique described in the question.
