1. 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.

2. What is a severe adverse effect of iron supplementation?

A. Seizures
B. Dry mouth
C. Edema
D. Serotonin syndrome

Correct answer: A

Rationale: A severe adverse effect of iron supplementation is seizures. Iron toxicity can lead to symptoms such as abdominal pain, vomiting, bloody diarrhea, lethargy, and in severe cases, seizures. It is important for individuals taking iron supplements to follow recommended dosages to prevent adverse effects.

3. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?

A. Gram stain
B. Culture
C. Sensitivity
D. Specific gravity

Correct answer: C

Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.

4. During transfusion of a unit of whole blood, a nurse is assessing a client who develops a cough, shortness of breath, elevated blood pressure, and distended neck veins. The nurse should anticipate a prescription for which of the following medications?

A. Epinephrine
B. Lorazepam
C. Furosemide
D. Diphenhydramine

Correct answer: C

Rationale: The client's symptoms indicate circulatory overload, which can occur during blood transfusions. Furosemide, a loop diuretic, is commonly prescribed in such cases to help relieve manifestations of circulatory overload by promoting diuresis and reducing fluid volume. Epinephrine is used for severe allergic reactions, lorazepam for anxiety or seizures, and diphenhydramine for mild allergic reactions or as a sedative. Therefore, the correct choice is Furosemide (C) to manage circulatory overload during a blood transfusion.

5. Which of the following medications is a bronchodilator?

A. Albuterol
B. Omeprazole
C. Ondansetron
D. Senna

Correct answer: A

Rationale: Albuterol is classified as a bronchodilator, which is commonly used to treat conditions like asthma by relaxing the muscles in the airways and increasing airflow to the lungs. Omeprazole is a proton pump inhibitor used to reduce stomach acid production, while ondansetron is an anti-nausea medication, and senna is a laxative.
