Nursing Elites

1. A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?

• A. The fingers curl tightly, and the toes curl forward.
• B. The toes flare, and the big toe is dorsiflexed.
• C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
• D. The infant turns to the side that is touched.

Correct answer: B

Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.

2. A nurse is preparing to test the function of cranial nerve XI. Which action does the nurse take to test this nerve?

• A. Asking the client to stick out his or her tongue and watching for tremors
• B. Touching the posterior pharyngeal wall with a tongue blade and noting the gag reflex
• C. Depressing the client's tongue with a tongue blade and noting pharyngeal function as the client says 'ah'
• D. Placing his or her hands on the client's shoulders and asking the client to shrug the shoulders against resistance from the nurse's hands

Correct answer: D

Rationale: To assess the function of cranial nerve XI (spinal accessory nerve), the nurse examines the sternomastoid and trapezius muscles for equal size and strength. The correct method involves asking the client to rotate the head forcibly against resistance to the side of the chin and to shrug the shoulders against resistance from the nurse's hands. Choice A, asking the client to stick out the tongue and watching for tremors, is used to assess cranial nerve XII (hypoglossal nerve). Choice C, depressing the client's tongue with a tongue blade and noting pharyngeal function as the client says 'ah', is the technique for examining cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). Choice B, touching the posterior pharyngeal wall with a tongue blade and noting the gag reflex, is used to evaluate cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve), not cranial nerve XI.

3. 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.

4. What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?

• A. Dextrose concentrations below 20% can be safely administered through a peripheral IV; dextrose concentrations above 20% should not be administered through a peripheral IV.
• B. Dextrose concentrations below 5% can be safely administered through a peripheral IV; dextrose concentrations above 5% should not be administered through a peripheral IV.
• C. Dextrose concentrations below 10% can be safely administered through a peripheral IV; dextrose concentrations above 10% should not be administered through a peripheral IV.
• D. Dextrose concentrations above 5% can be safely administered through a peripheral IV; dextrose concentrations below 5% should not be administered through a peripheral IV.

Correct answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.

5. Which of the following are included in the Rights of Medication Administration? Select all that apply.

• A. Right dose, right time, right explanation, right client, right route
• B. Right dose, right time, right client, right route
• C. Right dose, right time, right client
• D. Right time, right explanation, right client

Correct answer: B

Rationale: The Rights of Medication Administration include the right client, right drug, right dose, right route, and right time. An additional right that is sometimes included is the right documentation. The correct answer includes the essential rights that must be ensured during medication administration. Choice A is incorrect as 'right explanation' is not part of the traditional Rights of Medication Administration. Choice B is incorrect as 'right explanation' is not included, and choice C is missing the right route. Choice D is incorrect as it lacks the right dose and right route.
