Nursing Elites

1. 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.

2. What type of immunity do vaccines provide?

• A. active
• B. passive
• C. transplacental
• D. active and passive

Correct answer: A

Rationale: Vaccines provide active immunity by stimulating the immune system to produce antibodies against specific pathogens. Choice B, passive immunity, is acquired from ready-made antibodies, not through vaccination. Choice C, transplacental immunity, is a form of passive immunity transferred from mother to infant, not acquired through vaccines. Therefore, the correct answer is active immunity.

3. An assessment of the skull of a normal 10-month-old baby should identify which of the following?

• A. closure of the posterior fontanel.
• B. closure of the anterior fontanel.
• C. overlap of cranial bones.
• D. ossification of the sutures.

Correct answer: B

Rationale: The correct answer is the closure of the anterior fontanel. By 10 months of age, the anterior fontanel should be closed. The posterior fontanel should actually close by the age of 2 months, making choice A incorrect. Overlap of cranial bones is not a typical finding in a normal 10-month-old baby's skull, so choice C is incorrect. Ossification of the sutures is an ongoing process in skull development and should not be a definitive indicator at this age, making choice D incorrect.

4. A nurse is auscultating for vesicular breath sounds in a client. Of which quality would the nurse expect these normal breath sounds to be?

• A. Harsh
• B. Hollow
• C. Tubular
• D. Rustling

Correct answer: D

Rationale: The correct answer is D: 'Rustling.' Vesicular breath sounds are described as rustling and resemble the sound of wind blowing through trees. Harsh, hollow, and tubular sounds are associated with bronchial (tracheal) breath sounds, not vesicular breath sounds. Harsh sounds are high-pitched, hollow sounds are reverberating, and tubular sounds are like blowing air into a tube. Therefore, options A, B, and C are incorrect descriptions of vesicular breath sounds and are more characteristic of bronchial breath sounds.

5. 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.
