Nursing Elites

1. What is the therapeutic range for carbamazepine (Tegretol)?

• A. 7-12 mcg/mL
• B. 4-10 mcg/mL
• C. 10-14 mcg/mL
• D. 1-5 mcg/mL

Correct answer: B

Rationale: The therapeutic range for carbamazepine (Tegretol) is 4-10 mcg/mL. This range is established based on the optimal balance between effectiveness and safety. Choices A, C, and D are outside the therapeutic range for carbamazepine, which could lead to suboptimal treatment outcomes or increased risk of toxicity. Choice B (4-10 mcg/mL) is the correct range recommended for therapeutic efficacy while minimizing adverse effects.

2. A nurse is reviewing the medical record of an older client with presbycusis. Which finding would the nurse expect to note in the client's record?

• A. Difficulty hearing whispered words in the voice test
• B. Improved hearing ability during conversational speech
• C. Unilateral conductive hearing loss
• D. Difficulty hearing low-pitched tones

Correct answer: A

Rationale: Presbycusis, a sensorineural hearing loss, is the most common form of hearing loss in older adults. Typically, the loss is bilateral, resulting in difficulty hearing high-pitched tones. The condition is revealed when the client has difficulty hearing whispered words in the voice test and consonants during conversational speech. Choice A is correct because it reflects the expected finding in presbycusis. Choices B, C, and D are incorrect because presbycusis does not result in improved hearing ability during conversational speech, unilateral conductive hearing loss, or difficulty hearing low-pitched tones.

3. A nurse in the newborn nursery, assisting with data collection for a newborn, prepares to measure the chest circumference. The nurse places the tape measure around the infant at which location?

• A. In the axillary area
• B. At the level of the nipples
• C. Two inches below the nipples
• D. At the level of the umbilicus

Correct answer: B

Rationale: The chest circumference of the infant is measured at the level of the nipples. It is usually 2 to 3 cm smaller than the head circumference. The average chest circumference is 30.5 to 33 cm (12-13 inches). When there is molding of the head, the head and chest measurements may be equal at birth. Placing the tape measure at the level of the nipples ensures accuracy and consistency in newborn assessment. Options A, C, and D are incorrect as the chest circumference is specifically measured at the level of the nipples to obtain precise measurements.

4. A nurse is assisting with data collection regarding skin and peripheral vascular findings on a client in later adulthood. Which observation would the nurse expect to note as an age-related finding?

• A. Thin, ridged toenails
• B. Thick skin on the lower legs
• C. Loss of hair on the lower legs
• D. Bounding dorsalis pedis pulse

Correct answer: C

Rationale: In later adulthood, age-related findings include trophic changes associated with arterial insufficiency, such as thin, shiny skin; thin, ridged toenails; and loss of hair on the lower legs. These changes occur normally with aging. Thick skin on the lower legs would not be an expected age-related finding as it typically indicates chronic venous insufficiency. A bounding dorsalis pedis pulse is not typical in later adulthood and may indicate arterial insufficiency, which is not an age-related finding.

5. A healthcare provider is assisting with data collection on a client for the major risk factors associated with coronary artery disease (CAD). Which modifiable risk factor does the healthcare provider obtain data on from the client?

• A. Age
• B. Ethnicity
• C. Hypertension
• D. Genetic inheritance

Correct answer: C

Rationale: The correct answer is 'Hypertension.' Risk factors for CAD are categorized as modifiable and unmodifiable. Unmodifiable risk factors include age, sex, ethnicity, genetic predisposition, and family history of heart disease. Modifiable risk factors include increased concentrations of serum lipids, hypertension, cigarette smoking, obesity, and level of physical activity. In this case, hypertension is a modifiable risk factor that the healthcare provider would obtain data on. Choices A, B, and D are incorrect because age, ethnicity, and genetic inheritance are unmodifiable risk factors for CAD, not modifiable ones.
