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. 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.

3. While a client is on total parenteral nutrition, which of the following values should the nurse monitor closely?

• A. calcium
• B. magnesium
• C. glucose
• D. cholesterol

Correct answer: C

Rationale: Glucose should be monitored closely when a client is on total parenteral nutrition due to the high glucose concentration in the solutions. Monitoring glucose levels is crucial to prevent complications such as hyperglycemia or hypoglycemia. Calcium and magnesium are usually monitored to assess electrolyte imbalances, while cholesterol levels are not directly impacted by total parenteral nutrition. Therefore, choices A, B, and D are not the primary values that need close monitoring during total parenteral nutrition.

4. An allergic reaction is classified as what type of pharmacological effect?

• A. a therapeutic effect
• B. a side effect
• C. an adverse effect
• D. an incompatibility

Correct answer: C

Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.

5. A pregnant client is scheduled to undergo a transabdominal ultrasound, and the nurse provides information to the client about the procedure. The nurse provides which information?

• A. The procedure typically takes 10 to 30 minutes.
• B. She may need to drink fluids before the test and may not void until the test has been completed.
• C. A probe coated with gel will be inserted into the vagina.
• D. She will be positioned on her back, with her head elevated and turned slightly to one side.

Correct answer: B

Rationale: The correct answer is that the client may need to drink fluids before the test and may not void until the test has been completed. For a transabdominal ultrasound, the woman is positioned on her back with her head elevated and turned slightly to one side to prevent supine hypotension. A wedge or rolled blanket is placed under one hip to help her maintain this position comfortably. If a full bladder is necessary, the woman is instructed to drink several glasses of clear fluid 1 hour before the test and told that she should not void until the test has been completed. Warm mineral oil or transmission gel is spread over her abdomen, and the sonographer slowly moves a transducer over the abdomen to obtain a picture. The procedure typically takes 10 to 30 minutes, making choice A incorrect. Choice C is incorrect because a probe is not inserted into the vagina for a transabdominal ultrasound. Choice D is incorrect because the woman is positioned on her back with her head elevated and turned slightly to one side, not specifically on her back.
