ATI Pharmacology

Correct Answer: A

Rationale: To calculate the flow rate in mL/hr: (Volume in mL / Time in hours) = Flow rate in mL/hr. In this case, (100 mL / 0.5 hr) = 200 mL/hr. Therefore, the IV pump should be set to deliver 200 mL/hr to administer clindamycin 200 mg over 30 minutes.

Correct Answer: B

Rationale: The nurse should monitor the client for hypertension as a common adverse effect of epoetin alfa, which stimulates red blood cell production and can lead to increased blood pressure.

Correct Answer: A

Rationale: One of the potential adverse effects of fluoxetine and other SSRIs is a decreased desire for intimacy. It is important for the nurse to educate the client about this possible side effect to enhance understanding and promote informed decision-making.

Correct Answer: B

Rationale: The activated partial thromboplastin time (aPTT) is specifically used to monitor the effectiveness of heparin therapy. It should be maintained at 1.5 to 2 times the normal level. Monitoring aPTT helps ensure that the therapeutic range of heparin is achieved to prevent clot formation while minimizing the risk of bleeding complications.

Correct Answer: D

Rationale: Enoxaparin is a medication that should be administered as a subcutaneous injection in the abdomen to prevent bleeding complications. Massaging the injection site after administration should be avoided to reduce the risk of local irritation or bleeding. Rotating injection sites between the arms and thighs is a good practice for some medications but not recommended for Enoxaparin, which should be consistently given in the abdomen for optimal absorption and to avoid complications.
