Nursing Elites

1. The healthcare provider is planning care for a client at 30 weeks gestation who is experiencing preterm labor. Which medication is most important in preventing this fetus from developing respiratory distress syndrome?

• A. Ampicillin 1 gram IV push every 8 hours
• B. Betamethasone 12 mg deep IM
• C. Terbutaline 0.25 mg subcutaneously every 15 minutes for 3 doses
• D. Butorphanol tartrate 1 mg IV push every 2 hours as needed

Correct answer: B

Rationale: Betamethasone is a corticosteroid given to stimulate fetal lung maturity and reduce the risk of respiratory distress syndrome in preterm infants. Ampicillin (Choice A) is an antibiotic and does not prevent respiratory distress syndrome. Terbutaline (Choice C) is a tocolytic used to inhibit contractions and does not directly prevent respiratory distress syndrome. Butorphanol tartrate (Choice D) is an opioid analgesic and does not have a role in preventing respiratory distress syndrome in preterm infants.

2. If an individual receives a recessive gene for eye color from both parents, the:

• A. gender of the child will not determine the expression of that trait.
• B. recessive trait will be expressed in the child.
• C. recessive trait will be expressed in all the offspring.
• D. recessive trait will be suppressed, and the dominant trait will not be expressed.

Correct answer: B

Rationale: When an individual inherits a recessive gene for eye color from both parents, the recessive trait will be expressed in the child. This is because having two copies of the recessive gene overrides the presence of any dominant gene. Choice A is incorrect because the expression of the trait is determined by the genetic makeup, not the gender of the child. Choice C is incorrect as the expression of the recessive trait is certain when both parents pass on the recessive gene, but it does not mean that all offspring will express the trait. Choice D is incorrect because if both parents provide a recessive gene, the dominant trait will not be expressed in the child, but it does not mean it will be suppressed; rather, the recessive trait will be expressed.

3. A newborn is scheduled to start phototherapy using a lamp. Which of the following actions should the nurse include in the plan?

• A. Apply a thin layer of lotion to the newborn's skin every 8 hours.
• B. Give the newborn 1 oz of glucose water every 4 hours.
• C. Ensure the newborn's eyes are closed beneath the shield.
• D. Dress the newborn in a thin layer of clothing during therapy.

Correct answer: C

Rationale: During phototherapy using a lamp, it is crucial to protect the newborn's eyes from the light to prevent damage. Closing the newborn's eyes beneath the shield is essential for this purpose. Applying lotion to the skin (Choice A) is not recommended as it can intensify the effects of the phototherapy. Giving glucose water (Choice B) is unrelated to the phototherapy process and is not indicated. Dressing the newborn in clothing (Choice D) may hinder the effectiveness of the phototherapy by blocking the light exposure to the skin.

4. Individuals with Klinefelter syndrome produce:

• A. less estrogen than normal males.
• B. less testosterone than normal males.
• C. less adenine than normal males.
• D. less thymine than normal males.

Correct answer: B

Rationale: Individuals with Klinefelter syndrome have an extra X chromosome (XXY), leading to reduced production of testosterone, the primary male sex hormone. This deficiency can result in various physical and developmental characteristics associated with the syndrome. Estrogen levels may actually be relatively elevated due to the imbalance between testosterone and estrogen. Choices C and D are incorrect as adenine and thymine are nucleotide bases found in DNA and are not related to hormone production.

5. A primigravida arrives at the observation unit of the maternity unit because she thinks she is in labor. The nurse applies the external fetal heart monitor and determines that the fetal heart rate is 140 beats per minute and contractions are occurring irregularly every 10 to 15 minutes. Which assessment finding confirms to the nurse that the client is not in labor at this time?

• A. Membranes are intact.
• B. 2+ pitting edema in lower extremities.
• C. Contractions decrease with walking.
• D. Cervical dilation is 1 centimeter.

Correct answer: C

Rationale: The correct answer is C. Contractions that decrease with walking are typically indicative of false labor, as true labor contractions tend to intensify with activity. Choices A, B, and D are incorrect. A) Intact membranes are a normal finding and do not confirm the absence of labor. B) 2+ pitting edema in lower extremities is a sign of fluid retention and not directly related to labor status. D) Cervical dilation of 1 centimeter indicates some cervical changes, but it alone does not confirm active labor.
