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. A nurse is assisting with data collection regarding the motor development of a 24-month-old child. Which activities would the nurse expect the mother to report that the child can perform?

• A. Go to the bathroom without help
• B. Dress himself appropriately
• C. Put on and tie his shoes
• D. Align two or more blocks

Correct answer: A

Rationale: By 24 months of age, a child can perform various activities. While the child may be able to put on simple items of clothing, distinguishing front from back might still be a challenge. They may also be able to zip large zippers, put on shoes, wash and dry their hands, align two or more blocks, and turn book pages one at a time. However, the fine motor skill required to tie shoes is usually not developed at this age. Full independence in dressing, using the bathroom, and eating typically occurs around 4 to 5 years of age. Therefore, the correct expectation for a 24-month-old child would be aligning two or more blocks. Choices A, B, and C are incorrect as they represent skills that are usually achieved at a later age.

3. While taking the vital signs of a pregnant client admitted to the labor unit, a nurse notes a temperature of 100.6�F, pulse rate of 100 beats/min, and respirations of 24 breaths/min. What is the most appropriate nursing action based on these findings?

• A. Notify the registered nurse of the findings.
• B. Document the findings in the client's medical record.
• C. Recheck the vital signs in 1 hour.
• D. Continue collecting subjective and objective data.

Correct answer: A

Rationale: The correct answer is to notify the registered nurse of the findings. In a pregnant client, the normal temperature range is 98�F to 99.6�F, with a pulse rate of 60 to 90 beats/min and respirations of 12 to 20 breaths/min. A temperature of 100.4�F or higher, along with an increased pulse rate and faster respirations, suggests a possible infection. Immediate notification of the registered nurse is crucial for further evaluation and intervention. While documenting the findings is essential, the priority lies in promptly escalating abnormal vital signs for assessment and management. Rechecking vital signs in 1 hour may delay necessary interventions for a deteriorating condition. Continuing to collect data is relevant but should not delay informing the registered nurse when abnormal vital signs are present.

4. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part water and one part concentrate.
• D. When using powdered formula, mix two parts water and one part powder.

Correct answer: A

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly. Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.

5. When assisting the physician in performing transillumination of a client's scrotum, how should the nurse prepare for this procedure?

• A. Obtaining a flashlight and darkening the room
• B. Instructing the client to drink three glasses of water
• C. Instructing the client to take several deep breaths and bear down
• D. Telling the client that the procedure is very uncomfortable but that the discomfort will only last for a few moments

Correct answer: A

Rationale: When preparing for transillumination of the scrotum, the nurse should obtain a flashlight and darken the room. This is done to allow the strong flashlight to be shined from behind the scrotal contents. Normal scrotal contents do not appear on transillumination. Instructing the client to drink fluids or to take deep breaths and bear down is not part of the preparation for this procedure. Additionally, it is not necessary to inform the client that the procedure is uncomfortable as transillumination is a painless procedure.
