Nursing Elites

1. A woman asks, “How much alcohol can I safely drink while pregnant?” The nurse’s best response is:

• A. “The amount of alcohol that is safe during pregnancy is unknown.”
• B. “Consuming one or two beers or glasses of wine a day is considered safe for a healthy pregnant woman.”
• C. “Drinking three or more drinks on any given occasion is the only harmful type of drinking during pregnancy.”
• D. “You can have a drink to help you relax and get to sleep at night.”

Correct answer: “The amount of alcohol that is safe during pregnancy is unknown.”

Rationale: The correct answer is, “The amount of alcohol that is safe during pregnancy is unknown.” This response is appropriate because there is no known safe amount of alcohol consumption during pregnancy. Consuming any amount of alcohol during pregnancy can pose risks to the developing fetus, leading to conditions like fetal alcohol syndrome, which is a combination of mental and physical abnormalities in infants. Choices B, C, and D are incorrect. Choice B suggests that consuming one or two drinks a day is safe during pregnancy, which is not supported by current medical guidelines. Choice C incorrectly states that only drinking three or more drinks on any given occasion is harmful, when in reality, any amount of alcohol can be harmful to the fetus. Choice D is inappropriate as it suggests that having a drink to relax and sleep is acceptable during pregnancy, which is not the case.

2. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

• A. 0.9% sodium chloride
• B. 5% dextrose in water solution
• C. Sterile water
• D. Heparin sodium

Correct answer: 0.9% sodium chloride

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

3. The nurse is assigned to care for an infant with physiologic jaundice. Which action by the nurse would facilitate elimination of the bilirubin?

• A. Increasing the infant’s fluid intake
• B. Maintaining the infant’s body temperature at 98.6°F
• C. Minimizing tactile stimulation
• D. Decreasing caloric intake

Correct answer: Increasing the infant’s fluid intake

Rationale: Bilirubin is excreted through the kidneys, therefore increasing fluid intake can help facilitate its elimination. Maintaining the infant's body temperature is important for overall health but does not directly assist in eliminating bilirubin, making choice B incorrect. Choices C and D are irrelevant to bilirubin elimination in this scenario and do not address the specific issue of physiologic jaundice.

4. Narrow therapeutic index medications:

• A. are drug formulations with limited pharmacokinetic variability.
• B. have limited value and require no monitoring of blood levels.
• C. have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood
• D. have limited potency and side effects.

Correct answer: have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

5. When assessing a client with glaucoma, a nurse expects which of the following findings?

• A. Complaints of double vision
• B. Complaints of halos around lights
• C. Intraocular pressure of 15 mm Hg
• D. Soft globe on palpation

Correct answer: Complaints of halos around lights

Rationale: When assessing a client with glaucoma, a common finding is complaints of halos around lights. Other symptoms of glaucoma include loss of peripheral vision or blind spots, reddened sclera, firm globe, decreased accommodation, and occasional eye pain. Glaucoma may be asymptomatic until permanent damage to the optic nerve and retina occurs. Double vision is not a typical symptom of glaucoma. In terms of intraocular pressure, normal levels range from 10 to 21 mm Hg, making an intraocular pressure of 15 mm Hg within the normal range. A soft globe on palpation is not a typical finding in glaucoma.
