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 client with Kawasaki disease has bilateral congestion of the conjunctivae, dry cracked lips, a strawberry tongue, and edema of the hands and feet followed by desquamation of fingers and toes. Which of the following nursing measures is most appropriate to meet the expected outcome of positive body image?

• A. administering immune globulin intravenously
• B. assessing the extremities for edema, redness, and desquamation every 8 hours
• C. explaining progression of the disease to the client and their family
• D. assessing heart sounds and rhythm

Correct answer: C

Rationale: Educating the client and their family about the progression of Kawasaki disease is crucial for promoting a positive body image. By explaining when symptoms are expected to improve and resolve, the client and family can better understand that there will be no permanent disruption in physical appearance that could negatively impact body image. Administering immune globulin intravenously is a treatment for Kawasaki disease but does not directly address body image concerns. Assessing the extremities for edema, redness, and desquamation every 8 hours is important for monitoring the disease but does not directly address body image concerns. Assessing heart sounds and rhythm is essential for evaluating cardiac effects of Kawasaki disease but is not the most direct measure for promoting a positive body image.

3. A nurse assisting with data collection is preparing to auscultate the client's bowel sounds. The client tells the nurse that he ate lunch just 45 minutes ago. On the basis of this information, which finding does the nurse expect to note?

• A. Gurgling sounds
• B. Hypoactive sounds
• C. Low-pitched sounds
• D. An absence of sounds

Correct answer: A

Rationale: Bowel sounds are high-pitched, gurgling, cascading sounds that occur irregularly between five and 30 times a minute. In this scenario, since the client ate lunch just 45 minutes ago, the nurse would expect to note gurgling sounds as normal bowel activity. Hypoactive sounds (low-pitched) or an absence of sounds are usually associated with conditions such as abdominal surgery or inflammation of the peritoneum, not with recent food intake. Therefore, the correct answer is gurgling sounds, indicating normal bowel activity following a recent meal.

4. An LPN is tasked with checking the narcotic count on a medical-surgical unit. Which statement by the LPN requires further investigation?

• A. "I need a witness when I waste the leftover narcotics in the client's PCA pump."?
• B. "I am going to check the facility's policy for how to dispose of this controlled substance."?
• C. "I left the narcotics box unlocked after confirming the beginning of shift count was correct."?
• D. "The end of shift narcotics count is incorrect and needs to be reported."?

Correct answer: C

Rationale: The LPN's statement about leaving the narcotics box unlocked after confirming the beginning of shift count was correct requires further investigation. Narcotics should be locked and kept in a secure place during the shift to prevent unauthorized access and ensure patient safety. This statement raises concerns about medication security, which is critical in preventing diversion and ensuring patient safety. The other statements demonstrate appropriate actions: A) The LPN acknowledges the need for a witness when wasting leftover narcotics, ensuring proper documentation and accountability during medication waste. B) Checking the facility's policy for proper disposal of controlled substances shows awareness of regulatory compliance regarding controlled substances. D) Recognizing an incorrect end-of-shift narcotics count and planning to report it reflects the LPN's responsibility in maintaining accurate records and addressing discrepancies, which is essential for medication safety and accountability.

5. An amniocentesis is scheduled for a pregnant client in the third trimester. The nurse informs the client that the most common indication for amniocentesis during the third trimester is for which reason?

• A. Determination of whether alpha-fetoprotein (AFP) is present in the amniotic fluid
• B. Checking the amniotic fluid for intrauterine infection
• C. Determination of fetal lung maturity
• D. Checking the fetal cells for chromosomal abnormalities

Correct answer: C

Rationale: The most common indication for amniocentesis in the third trimester is the determination of fetal lung maturity. This assessment is essential to evaluate the fetus's readiness for extrauterine life. Checking for alpha-fetoprotein (AFP) in the amniotic fluid is more commonly associated with midtrimester amniocentesis to identify chromosomal abnormalities. Assessing for intrauterine infection is not a primary reason for amniocentesis in the third trimester. While checking fetal cells for chromosomal abnormalities is a common indication for midtrimester amniocentesis, it is not the most common indication in the third trimester.
