Nursing Elites

1. The LPN is taking care of a 176-pound client who has recently been diagnosed with diabetes. The primary healthcare provider has written an order for Lantus� (insulin glargine injection) 100 units/mL, using weight-based dosing of 0.2 units/kg per day. The LPN should prepare ____ units for administration.

• A. 12
• B. 35
• C. 16
• D. 9

Correct answer: B

Rationale: To calculate the correct dosage, first convert the client's weight from pounds to kilograms. As 1 kg = 2.2 pounds, 176 pounds � 2.2 = 80 kg. The client should receive 0.2 units for every kilogram, which equals 16 units. Therefore, the total amount to prepare is 16 units x 100 units/mL = 1600 units. Considering the medication concentration of 100 units/mL, 1600 units � 100 units/mL = 16 mL. However, since the question asks for the number of units, the final answer is 16 units x 2 injections = 32 units. Therefore, the LPN should prepare 32 units for administration.

2. The LPN is caring for a client taking Lipitor (Atorvastatin). Which of these statements would indicate that the client may need reinforced teaching?

• A. "I take my Lipitor with a glass of milk after my breakfast."?
• B. "I take my Lipitor and wait 30 minutes before taking my other medications."?
• C. "I take my Lipitor 30 minutes after I eat something."?
• D. "I take my Lipitor and my other morning medications with my grapefruit juice at breakfast."?

Correct answer: D

Rationale: The correct answer is, 'I take my Lipitor and my other morning medications with my grapefruit juice at breakfast.' This statement indicates a need for reinforced teaching because grapefruit juice should be avoided when taking Lipitor. Grapefruit juice blocks the enzymes needed to break down the drug, which leads to excessive amounts of the drug in the body. Choices A, B, and C show appropriate timing and administration of Lipitor, whereas choice D poses a potential risk due to the interaction between grapefruit juice and Lipitor.

3. 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.

4. What is the primary theory that explains a family's concept of health and illness?

• A. Health Belief Model
• B. Education Factor
• C. Family Health Belief Model
• D. Family Dynamics Model

Correct answer: A

Rationale: The correct answer is the Health Belief Model. The Health Belief Model is a widely recognized theory that explains individuals' perceptions and behaviors related to health and illness. It considers factors such as perceived susceptibility, severity of health issues, benefits of action, and barriers to taking action. Choices B, C, and D are incorrect. Choice B, 'Education Factor,' is too general and does not specifically address a family's concept of health and illness. Choice C, 'Family Health Belief Model,' is a combination of terms and not a recognized theory. Choice D, 'Family Dynamics Model,' focuses on family interactions rather than explaining a family's concept of health and illness.

5. Which of the following physical findings indicates that an 11-12-month-old child is at risk for developmental dysplasia of the hip?

• A. refusal to walk
• B. not pulling to a standing position
• C. negative Trendelenburg sign
• D. negative Ortolani sign

Correct answer: B

Rationale: The correct answer is 'not pulling to a standing position.' If an 11-12-month-old child is unable to pull to a standing position, it can indicate a risk for developmental dysplasia of the hip. By 15 months of age, children should be walking, so delayed standing can be a red flag. The Trendelenburg sign is associated with gluteus medius muscle weakness, not hip dysplasia, making choice C incorrect. The Ortolani sign is used to detect congenital hip subluxation or dislocation, not developmental dysplasia, making choice D incorrect.
