Q21All of the following are potential effects of beta-blockers except:
✓ Correct answer: C. Increased heart rate
Answer: Increased heart rate Beta-blockers are medications that reduce blood pressure by blocking the effects of the hormone epinephrine, also known as adrenaline. They are commonly used to treat high blood pressure, angina, heart rhythm disorders, and other heart-related conditions. The typical effects of beta-blockers include decreased heart rate, fatigue, cold extremities, and lowering of blood pressure.
Q22You are preparing to administer a dose of Digoxin to a patient. The patient has been prescribed an antihypertensive medication, Lisinopril. Before administering these medications, you should:
✓ Correct answer: A. Check the patient's blood pressure and apical pulse rate
Before administering Digoxin and Lisinopril, it is essential to check the patient's blood pressure and apical pulse rate. Digoxin affects heart rate and should only be administered when the apical pulse rate is within safe limits. Lisinopril can lower blood pressure, so it is crucial to monitor these vital signs before administration.
Q23Your patient has just completed a colonoscopy. What symptom should you anticipate following this procedure?
✓ Correct answer: B. Abdominal cramping and gas
After a colonoscopy, it is common for patients to experience abdominal cramping and gas due to the air used during the procedure to inflate the colon. These symptoms are usually temporary.

✓ Correct answer: C. The patient loses 1-2 pounds per week during diuretic therapy
Answer: The patient loses 1-2 pounds per week during diuretic therapy Weight loss and improved fluid balance indicate the therapeutic efficacy of diuretic therapy. In this example, the patient's serum potassium level is low, urine output is too low, and blood pressure is too high.
Q27During a safety round, the nurse notices the patient monitor is not functioning. What is the appropriate action for the nurse to take?
✓ Correct answer: D. Place a tag labeling the equipment as out of order and submit a work order to engineering
Placing a tag labeling the equipment as out of order and submitting a work order to engineering is the correct action. This helps prevent the use of faulty equipment, which could harm patients. Notifying engineering ensures that the monitor can be assessed and repaired promptly.
Q28Under what circumstances should a healthcare worker use gloves and gowns?
✓ Correct answer: A. When there is a risk of exposure to blood or bodily fluids
Gloves and gowns are barrier protections used to shield healthcare workers from exposure to potentially infectious materials such as blood or bodily fluids. They should be used whenever there is a risk of contact with these materials.
Q29Which of the following situations would require the nurse to implement contact isolation precautions? Select all that apply.
✓ Correct answer: A. Methicillin-resistant Staphylococcus aureus (MRSA) infection
Contact precautions are for infections, diseases, or germs that are spread by touching the patient or items in the room, such as MRSA, VRE, and impetigo. Patients with these infections should be placed in a private room or cohort room (if necessary), and healthcare workers should wear gloves and gowns when entering the room. Tuberculosis requires airborne precautions, and influenza requires droplet precautions.
Q30A patient is admitted with a wound infection after recent overseas surgery. The medical history indicates a high likelihood of an infection transmitted via contact with contaminated surfaces or equipment. Which of the following organisms is the patient most likely infected with? Select all that apply.
✓ Correct answer: A. Vancomycin-resistant Enterococcus (VRE)
MRSA, VRE, and C. diff are often transmitted through contact with contaminated surfaces or equipment in healthcare settings. They are common causes of hospital-acquired infections. Strict infection control practices like hand hygiene and equipment sterilization are essential to prevent their spread. In contrast, Mycobacterium tuberculosis and Neisseria meningitidis are primarily transmitted through respiratory droplets.
