Nursing Elites

1. Intramuscular (IM) phytonadione (vitamin K) 0.5 mg is prescribed for a newborn. After the medication is prepared, in which anatomic site does the nurse administer it?

• A. Rectus femoris muscle
• B. Deltoid muscle
• C. Gluteal muscle
• D. Vastus lateralis muscle

Correct answer: D

Rationale: Vitamin K is administered to newborn infants to help prevent hemorrhagic disease. The best site for intramuscular injection in infants is the vastus lateralis muscle. This site is preferred due to its location away from the sciatic nerve, femoral artery, and vein, reducing the risk of complications. The rectus femoris muscle may be used if necessary; however, it is less favorable than the vastus lateralis due to its proximity to vital structures, making injections there more hazardous. The deltoid muscle is not typically used for IM injections in newborns. The gluteal muscles should be avoided until the child has been walking for at least a year, as they are poorly developed and close to the sciatic nerve.

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 nurse assisting with data collection is testing the cochlear portion of the acoustic nerve (cranial nerve VIII). Which action does the nurse take to test this nerve?

• A. Asking the client to raise their eyebrows and looking for symmetry
• B. Asking the client to clench the teeth, then palpating the masseter muscles just above the mandibular angle
• C. Asking the client to close the eyes and then identify light and sharp touch with a cotton ball and a pin on both sides of the face
• D. Asking the client to close their eyes and then indicate when a ticking watch is heard as the nurse brings the watch closer to the client's ear

Correct answer: D

Rationale: To test the cochlear portion of the acoustic nerve (cranial nerve VIII), the nurse should have the client close their eyes and indicate when a ticking watch is heard as the nurse moves the watch closer to the client's ear. This action assesses the client's ability to perceive auditory stimuli, as the cochlear portion of the acoustic nerve is responsible for hearing. Choices A, B, and C are incorrect. Asking the client to raise their eyebrows to check for symmetry is a method to test the facial nerve (cranial nerve VII). Asking the client to clench their teeth and palpating the masseter muscles tests the motor component of the trigeminal nerve. Having the client identify light and sharp touch on both sides of the face is a way to test the sensory component of the trigeminal nerve (cranial nerve V).

4. A nurse assisting with data collection uses the back of the hand to feel the client's skin on both arms and notes that the skin is warm. The nurse makes which determination?

• A. The client has a fever.
• B. The skin temperature is normal.
• C. The client needs to drink additional fluids.
• D. The client needs to have the blanket removed.

Correct answer: B

Rationale: To assess skin temperature, the nurse would first note the temperature of their own hands. Then, using the backs of the hands to palpate the client's skin bilaterally, warmth suggests normal circulatory status if the skin is warm and the temperature is equal bilaterally. The hands and feet may feel slightly cooler in a cool environment. Options A, C, and D are incorrect responses. A warm skin temperature does not indicate a fever, the need for additional fluids, or the need to have the blanket removed.

5. An LPN is tasked with checking the narcotic count on a medical-surgical unit. Which statement by the LPN requires further investigation?

• A. "I need a witness when I waste the leftover narcotics in the client's PCA pump."?
• B. "I am going to check the facility's policy for how to dispose of this controlled substance."?
• C. "I left the narcotics box unlocked after confirming the beginning of shift count was correct."?
• D. "The end of shift narcotics count is incorrect and needs to be reported."?

Correct answer: C

Rationale: The LPN's statement about leaving the narcotics box unlocked after confirming the beginning of shift count was correct requires further investigation. Narcotics should be locked and kept in a secure place during the shift to prevent unauthorized access and ensure patient safety. This statement raises concerns about medication security, which is critical in preventing diversion and ensuring patient safety. The other statements demonstrate appropriate actions: A) The LPN acknowledges the need for a witness when wasting leftover narcotics, ensuring proper documentation and accountability during medication waste. B) Checking the facility's policy for proper disposal of controlled substances shows awareness of regulatory compliance regarding controlled substances. D) Recognizing an incorrect end-of-shift narcotics count and planning to report it reflects the LPN's responsibility in maintaining accurate records and addressing discrepancies, which is essential for medication safety and accountability.
