1. The factor that most determines drug distribution is:

Correct answer: vascular perfusion of the tissue or organ.

Rationale: The correct answer is 'vascular perfusion of the tissue or organ.' Drug distribution is primarily determined by how well the circulatory system delivers the drug to various tissues and organs. Adequate perfusion ensures proper distribution of the drug throughout the body. While the salt form (choice B), drug interactions (choice C), and steady state (choice D) can influence drug efficacy and metabolism, they are not as crucial as vascular perfusion for the initial distribution of a drug.

2. Which is an example of a sentinel event?

Correct answer: A client scheduled for knee replacement surgery had an above-the-knee amputation performed.

Rationale: Yes! A sentinel event is an unexpected occurrence causing death or serious injury. In this case, a client who was scheduled for knee replacement surgery but had an above-the-knee amputation performed instead represents a sentinel event as it resulted in serious harm that was not intended. The other choices do not meet the criteria for a sentinel event. Choice A describes a natural progression for a terminally ill client, choice B shows an incidental finding from a test, and choice C involves a preventable fall leading to an injury but not a sentinel event.

3. A 13-year-old girl is admitted to the ER with lower right abdominal discomfort. What should the admitting nurse do first?

Correct answer: Provide pain reduction techniques without administering medication.

Rationale: In a case of lower right abdominal discomfort, the first step should be to provide pain reduction techniques without administering medication. Administering pain medication or starting a central line should not be done without medical orders. Placing the patient in a right sidelying position may help with pressure relief, but addressing pain reduction techniques without medication is the initial priority in this scenario. It is essential to assess the patient further, consult with a healthcare provider, and follow the appropriate protocols before administering any medication or invasive procedures like starting a central line.

4. A client begins a regimen of chemotherapy. Her platelet count falls to 98,000. Which action is least likely to increase the risk of hemorrhage?

Correct answer: Implement reverse isolation.

Rationale: The correct answer is to implement reverse isolation. Reverse isolation is a protective measure used to protect patients from infections, not to affect the risk of hemorrhage. Testing all excreta for occult blood (Choice A) is important to monitor for signs of internal bleeding. Using a soft toothbrush or foam cleaner for oral hygiene (Choice B) is recommended to prevent gum bleeding. Avoiding IM injections (Choice D) is crucial to reduce the risk of bleeding in a client with a low platelet count. Therefore, among the given options, implementing reverse isolation is the least likely to increase the risk of hemorrhage.

5. Which of the following is an inappropriate item to include in planning care for a severely neutropenic client?

Correct answer: Transfuse neutrophils (granulocytes) to prevent infection.

Rationale: The correct answer is to transfuse neutrophils (granulocytes) to prevent infection. Granulocyte transfusion is not routinely indicated to prevent infection in neutropenic clients. While neutrophils are essential in fighting infections and are beneficial in selected populations of infected, severely granulocytopenic clients who do not respond to antibiotics and are expected to experience prolonged suppression of granulocyte production, routine granulocyte transfusion is not recommended. Choices B, C, and D are appropriate interventions for a severely neutropenic client. Prohibiting fresh flowers and plants helps reduce the risk of exposure to environmental pathogens. Avoiding rectal suppositories minimizes the risk of introducing harmful bacteria. Excluding raw vegetables from the diet reduces the likelihood of foodborne infections.
