Nursing Elites

1. How can medication bound to protein affect drug availability?

• A. enhanced drug availability
• B. rapid distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. increased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.

2. The nurse observes bilateral bruises on the arms of an elderly client in a long-term care facility. Which of the following questions should the nurse ask this client?

• A. "How did you get those bruises?"?
• B. "Did someone grab you by your arms?"?
• C. "Do you fall often?"?
• D. "What did you bump against?"?

Correct answer: B

Rationale: When addressing suspected abuse, it is crucial to ask direct questions to determine the cause of injuries. Choice B is the most appropriate as it directly inquires about the possibility of someone grabbing the client's arms, which could indicate abuse. This question can help uncover potential abuse and provide necessary intervention. Choices A, C, and D are less direct and may not elicit the critical information needed to address abuse effectively. Clients often hesitate to report abuse due to feelings of shame and fear of retaliation, making a direct approach essential in such situations.

3. During a well-baby check of a 6-month-old infant, the nurse notes abrasions and petechiae of the palate. The nurse should:

• A. inquire about the possibility of sexual abuse.
• B. ask about the types of foods the child is eating.
• C. request to see the type of bottle used for feedings.
• D. question the parent about objects the child plays with.

Correct answer: A

Rationale: The correct answer is to inquire about the possibility of sexual abuse. Injuries to the soft palate such as bruising, abrasions, and petechiae can be signs of sexual abuse in infants. While oral sex may not leave significant physical evidence, these findings should raise suspicion. Option A is correct as it focuses on addressing potential abuse. Options B, C, and D are incorrect because the child's diet, the type of bottle used for feedings, and play objects are not likely related to the observed injuries. The presence of oral injuries suggests considering sexual abuse rather than other factors.

4. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

• A. 0.9% sodium chloride
• B. 5% dextrose in water solution
• C. Sterile water
• D. Heparin sodium

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

5. Which task should not be performed by the licensed practical nurse?

• A. Inserting a Foley catheter
• B. Discontinuing a nasogastric tube
• C. Obtaining a sputum specimen
• D. Initiating a blood transfusion

Correct answer: D

Rationale: A licensed practical nurse should not initiate a blood transfusion. LPNs can assist with transfusions and verify ID numbers but should not be assigned to initiate the procedure. Inserting Foley catheters, discontinuing nasogastric tubes, and obtaining sputum specimens are within the scope of practice for LPNs. Therefore, options A, B, and C are tasks that LPNs can perform, making them incorrect choices.
