A client has a prescription for Heparin. Which of the following laboratory tests should be monitored while the client is receiving Heparin?
- A. Prothrombin time (PT)
- B. Complete blood count (CBC)
- C. International normalized ratio (INR)
- D. Activated partial thromboplastin time (aPTT)
Correct Answer: D
Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor while a client is receiving Heparin. This test is used to assess the therapeutic levels of heparin in the blood, ensuring that the dose is within the safe and effective range. Monitoring aPTT helps healthcare providers adjust the dosage of Heparin to prevent complications such as bleeding or clotting.

When administering a Serotonin Antagonist, what is important to monitor for?
- A. Intake and output
- B. Mental status changes
- C. Respiratory rate
- D. Anorexia

Rationale: When administering a Serotonin Antagonist, monitoring mental status changes is crucial.

It is essential to assess for any changes in behavior, mood, or cognition to ensure patient safety and prompt intervention if needed.
Regarding drugs used in the treatment of status epilepsy:
- A. phenytoin is useful in status for its sedating as well as anticonvulsant activity
- B. phenytoin may be diluted in both saline and dextrose
- C. the effect of diazepam is long lasting
- D. respiratory depression is a common complication of phenobarbitone
Correct Answer: D
Rationale: Phenytoin controls status epilepticus via anticonvulsant action, not sedation, so that's false. It precipitates in dextrose, only saline-compatible, making that false. Diazepam's effect is short-lived, not long-lasting, so that's incorrect. Phenobarbitone commonly causes respiratory depression, a true statement, due to CNS suppression. Phenytoin's rate is 50 mg/min max. This side effect limits phenobarbitone's use, requiring ventilatory support in status management.
Restoration of blood flow results through the dissolution of clot by:
- A. fibrin
- B. plasmin
- C. thrombin
- D. prothrombin
Correct Answer: B
Rationale: Plasmin is an enzyme that is responsible for breaking down fibrin, a protein that forms blood clots. When an area of vessel needs to have its blood flow restored, such as after a clot has formed, plasmin is activated to dissolve the clot. By breaking down the fibrin mesh of the clot, plasmin helps restore normal blood flow in the affected vessel. Therefore, the restoration of blood flow results through the dissolution of clot by plasmin, making option B the correct answer.
