Nursing Elites

1. A nurse is determining the fetal heart rate (FHR) and places the fetoscope on the mother's abdomen to count the FHR. The nurse simultaneously palpates the mother's radial pulse and notes that it is synchronized with the sounds heard through the fetoscope. Which action should the nurse take?

• A. Count the FHR for 60 seconds, ensuring that it is synchronized consistently with the mother's radial pulse.
• B. Move the fetoscope to another area on the mother's abdomen to locate the fetal heart.
• C. Ask the mother to lie still while both the FHR and the radial pulse rate are counted.
• D. Count the FHR for 30 seconds and then count the radial pulse rate of the mother for 30 seconds.

Correct answer: B

Rationale: When auscultating the fetal heart rate, the nurse would place the fetoscope on the maternal abdomen, over the fetal back. The nurse would then palpate the mother's radial pulse. If her pulse is synchronized with the sounds from the fetoscope, the nurse would move the fetoscope to another area on the mother's abdomen to locate the FHR. The nurse needs to be sure that the FHR is what is actually being heard. Other sounds that may be heard are the funic sound (blood flowing through the umbilical cord) and the uterine sound (blood flowing through the uterine vessels). The funic sound is synchronized with the FHR; the uterine sound is synchronized with the mother's pulse. Therefore, moving the fetoscope to a different area will help in accurately locating and counting the fetal heart rate. Choice A is incorrect because counting for 60 seconds without changing the position may not address the issue of accurately locating the FHR. Choice C is incorrect as it does not address the need to reposition the fetoscope to locate the fetal heart. Choice D is incorrect because counting the FHR and the radial pulse rate separately may not help in differentiating the two sounds.

2. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

3. A client in labor complains of back discomfort. Which position will best aid in relieving the discomfort? What position should the nurse encourage the mother to assume?

• A. Prone
• B. Standing
• C. Supine
• D. Hands and knees

Correct answer: D

Rationale: During back labor, when the back of the fetal head puts pressure on the woman's sacral promontory, the hands-and-knees position is encouraged. This position helps the fetus move away from the sacral promontory, reducing back pain and enhancing the internal-rotation mechanism of labor. A prone position would be difficult for the woman to assume and not helpful in relieving back discomfort. The supine position is risky due to supine hypotension, while standing may increase pressure, worsening backache.

4. When obtaining a health history on a menopausal woman, which information should a nurse recognize as a contraindication for hormone replacement therapy?

• A. family history of stroke
• B. ovaries removed before age 45
• C. frequent hot flashes and/or night sweats
• D. unexplained vaginal bleeding

Correct answer: D

Rationale: When obtaining a health history on a menopausal woman, unexplained vaginal bleeding should be recognized as a contraindication for hormone replacement therapy. This is because it can be a sign of underlying issues that need to be addressed before starting hormone therapy. A family history of stroke is not a contraindication for hormone replacement therapy unless the woman herself has a history of stroke or blood-clotting events. Ovaries removed before age 45 is not a contraindication for hormone replacement therapy. Frequent hot flashes and/or night sweats can be relieved by hormone replacement therapy; therefore, they are not contraindications.

5. Central venous access devices (CVADs) are frequently utilized to administer chemotherapy. What is an advantage of using CVADs for chemotherapeutic agent administration?

• A. CVADs are more expensive than a peripheral IV.
• B. Weekly administration is possible.
• C. Chemotherapeutic agents can be caustic to smaller veins.
• D. The client or family can administer the drug at home.

Correct answer: C

Rationale: The correct advantage of using CVADs for chemotherapeutic agent administration is that chemotherapeutic agents can be caustic to smaller veins. Many chemotherapeutic drugs are vesicants, which can cause tissue damage even in low concentrations. Using a CVAD to administer these agents into a large vein is optimal as it reduces the risk of damage. Choice A is incorrect as CVADs are actually more expensive than a peripheral IV, making it a disadvantage. Choice B is incorrect because the frequency of administration depends on the specific drug being administered, not on the access device, so it does not represent a universal advantage. Choice D is incorrect because IV chemotherapeutic agents are typically not self-administered at home; they are usually given in a hospital, outpatient, or clinic setting, making it an invalid advantage of using CVADs.
