What is a side effect of Heparin?
- A. nausea
- B. diarrhea
- C. bleeding
- D. bronchospasms
Correct Answer: C
Rationale: Heparin is an anticoagulant medication that works by preventing the formation of blood clots. One of the main side effects of heparin therapy is an increased risk of bleeding. Since heparin inhibits the body's ability to clot blood, it can lead to easy bruising, nosebleeds, gastrointestinal bleeding, or bleeding at the injection site. Patients on heparin therapy must be closely monitored for signs of bleeding, and their dosage may need to be adjusted to minimize this risk.

What is a side effect of Heparin?
- A. nausea
- B. diarrhea
- C. bleeding
- D. bronchospasms
Correct Answer: C
Rationale: A common side effect of Heparin, which is an anticoagulant medication, is the risk of bleeding. Heparin works by preventing the formation of blood clots, which can lead to a bleeding risk as it inhibits the normal clotting process. Patients taking Heparin should be monitored closely for signs of bleeding, such as easy bruising, prolonged bleeding from minor cuts, or blood in the urine or stools. It is important for healthcare providers to closely monitor patients on Heparin therapy and adjust the dosage as needed to minimize the risk of excessive bleeding.
A nurse is providing administration instruction to the wife of a client going home on intermittent enteral nutrition. Which information should the nurse include?
- A. Clean the equipment between each feeding administration
- B. Once mixed, enteral feeding should hang no more than 8 hours
- C. Refrigerate any feeding that is not needed for a feeding
- D. Keep the area around the insertion site clean
Correct Answer: A
Rationale: Cleaning equipment between each enteral feeding is vital to prevent bacterial contamination, as residual formula can foster microbial growth, risking infections like gastroenteritis in a client already nutritionally compromised. While limiting hang time is important, evidence suggests a 4-hour maximum, not 8, to minimize spoilage-though this isn't the focus here. Refrigerating unused feeding preserves its integrity, preventing degradation or bacterial proliferation, which is critical for safety. Keeping the insertion site clean reduces infection risk at the tube entry, a common complication in enteral therapy. Cleaning equipment stands out as a proactive step the wife can take between feedings, directly impacting hygiene and client safety, whereas other points address storage or site care, which, while essential, are secondary to the immediate post-feeding action of equipment maintenance in this context.
Depression that occurs during cold winter months would be classified as
- A. baby blues
- B. bipolar disorder
- C. seasonal affective disorder
- D. obsessive-compulsive disorder
Correct Answer: C
Rationale: Seasonal affective disorder (SAD) ties depression to winter-less light, per psychiatry-unlike baby blues (postpartum), bipolar (cycles), or OCD (obsessions). SAD's seasonal link defines it, matching symptoms.
The specificity of the adrenergic blocking agents allows the clinician to select a drug to do what?
- A. Have the desired effect
- B. Multiply undesired effects
- C. Increase specificity with higher serum blood levels
- D. Improving concentration in the body
Correct Answer: A
Rationale: This specificity allows the clinician to select a drug that will have the desired therapeutic effects without the undesired effects that occur when the entire sympathetic nervous system is blocked. In general, however, the specificity of adrenergic blocking agents depends on the concentration of drug in the body. Most specificity is lost with higher serum drug levels. The nurse should understand the importance of drug specificity to ensure safe and effective administration.
The following are anticoagulants that do not require monitoring of INR:
- A. Rivaroxaban
- B. Apixaban
- C. Dabigatran
- D. All of the above
Correct Answer: D
Rationale: These are direct oral anticoagulants (DOACs), which do not require regular INR monitoring.
