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. What is the intent of the Patient Self Determination Act (PSDA) of 1990?

• A. Enhance personal control over healthcare decisions.
• B. Encourage medical treatment decision making prior to need.
• C. Establish a federal standard for living wills and durable powers of attorney.
• D. Emphasize client education.

Correct answer: B

Rationale: The correct answer is B: The purpose of the PSDA is to encourage medical treatment decision-making before it becomes necessary. This legislation aims to empower individuals to make their own healthcare choices in advance. Choice A is incorrect because while enhancing personal control over healthcare decisions is important, the primary goal of the PSDA is to facilitate medical decision-making before the need arises. Choice C is incorrect as the PSDA does not establish a federal standard for living wills and durable powers of attorney; instead, it encourages individuals to create their own advance directives according to state-specific regulations. Choice D is incorrect because while client education is valuable, the main focus of the PSDA is on empowering individuals to plan for their future healthcare needs.

3. After delivering a healthy newborn 1 hour ago, a nurse notes a woman's radial pulse rate is 55 beats/min. What action should the nurse take based on this finding?

• A. Reporting the finding to the healthcare provider immediately
• B. Helping the woman stay in bed and rest
• C. Documenting the finding
• D. Performing active and passive range-of-motion exercises

Correct answer: C

Rationale: After delivery, bradycardia (pulse rate 50-70 beats/min) may occur, reflecting the large amount of blood returning to the central circulation after delivery of the placenta. The increase in central circulation results in increased stroke volume, allowing a slower heart rate to provide adequate maternal circulation. A pulse rate of 55 beats/min falls within the normal range post-delivery, so there is no need to notify the healthcare provider immediately. It is important for the client to remain on bed rest in the immediate postpartum period to prevent complications. While range-of-motion exercises are beneficial for a client on bed rest, it is not the priority based on the data provided. Therefore, the most appropriate nursing action is to document the finding for accurate record-keeping and monitoring of the client's condition.

4. How often should the intravenous tubing on total parenteral nutrition solutions be changed?

• A. every 24 hours
• B. every 36 hours
• C. every 48 hours
• D. every 72 hours

Correct answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.

5. A nurse is preparing to auscultate for the presence of bowel sounds in a client who has just undergone surgery. The nurse places the stethoscope in which abdominal quadrant first?

• A. Left upper quadrant
• B. Left lower quadrant
• C. Right upper quadrant
• D. Right lower quadrant

Correct answer: D

Rationale: The correct answer is the right lower quadrant. The nurse starts auscultating in this quadrant at the ileocecal valve as bowel sounds are normally always present there. Then, the nurse proceeds to listen for bowel sounds in the other quadrants. Choices A, B, and C are incorrect as the initial placement of the stethoscope should be in the right lower quadrant to assess bowel sounds post-surgery.
