1. Why might the physician order antibiotics to be given through the central venous access device (CVAD) rather than through a peripheral IV line if the CVAD becomes infected?

• A. To prevent infiltration of the peripheral line
• B. To reduce the pain and discomfort associated with antibiotic administration in a small vein
• C. To lessen the chance of an allergic reaction to the antibiotic
• D. To attempt to eliminate microorganisms in the catheter and prevent having to remove it

Correct answer: D

Rationale: When a patient's central venous access device (CVAD) becomes infected, administering antibiotics through the line is essential to attempt to eliminate microorganisms within the catheter. The goal is to prevent the necessity of removing the catheter, which might be required if the infection persists. Choice A, 'To prevent infiltration of the peripheral line,' is incorrect as the priority is addressing the catheter infection, not preventing issues with a peripheral line. Choice B, 'To reduce the pain and discomfort associated with antibiotic administration in a small vein,' is not relevant to the rationale for choosing the CVAD for antibiotic administration. Choice C, 'To lessen the chance of an allergic reaction to the antibiotic,' is also incorrect as the main focus is managing the catheter-associated infection rather than allergy prevention.

2. 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.

3. Activities of effective supervisors can be task-related or people-related activities. An example of a task-related supervisory activity is:

• A. coaching.
• B. evaluating.
• C. delegating.
• D. facilitating.

Correct answer: C

Rationale: Delegating is the act of assigning work to those capable and competent to do the work, making it a task-related supervisory activity. Coaching, evaluating, and facilitating are people-related supervisory activities. Coaching involves guiding and developing individuals, evaluating entails assessing performance, and facilitating focuses on enabling tasks and processes. These activities are more centered on interacting with and supporting people rather than directly assigning tasks. Therefore, in the context of task-related activities, delegating stands out as the correct choice.

4. After a client undergoes a left lower lobe lung resection for lung cancer, which post-operative measure would typically be included in the plan?

• A. Closed chest drainage
• B. A tracheostomy
• C. A mediastinal tube
• D. Percussion vibration and drainage

Correct answer: A

Rationale: After a lung resection, such as the removal of the left lower lobe for lung cancer, closed chest drainage is a common post-operative measure to help drain any excess air or fluid from the chest cavity. A tracheostomy is not typically needed for this procedure, so choice B is incorrect. Similarly, a mediastinal tube is not routinely inserted following a left lower lobe lung resection, making choice C incorrect. Percussion vibration and drainage are not indicated for this type of surgery, so choice D is also incorrect. Therefore, the correct answer is closed chest drainage.

5. Which of the following clients should refrain from therapy with the thiazide diuretic hydrochlorothiazide?

• A. a client with renal impairment
• B. a client with hypertension
• C. a client with diabetes mellitus, type II
• D. a client with renal calculi (kidney stones)

Correct answer: C

Rationale: The correct answer is a client with diabetes mellitus, type II. Thiazide diuretics like hydrochlorothiazide can cause metabolic abnormalities, including elevated blood glucose levels. This increase is linked to diuretic-induced potassium deficiency, which reduces insulin secretion, leading to higher plasma glucose levels. Thiazides are commonly used in clients with renal impairment and hypertension. Moreover, thiazides decrease calcium excretion, reducing the risk of renal calculi, so it is not contraindicated for clients with kidney stones. Therefore, clients with diabetes mellitus, type II should avoid therapy with hydrochlorothiazide due to the potential adverse effects on blood glucose levels.
