of Adult Health Nursing for the Practical
Nurse II Q&A with Rationale | Hondros
College of Nursing
1. A nurse is caring for a patient with Chronic Obstructive Pulmonary Disease (COPD) who is
receiving oxygen therapy. Which of the following delivery rates should the nurse clarify with
the healthcare provider?
A. 10 L/min via non-rebreather mask
B. 24% oxygen via Venturi mask
C. 6 L/min via simple face mask
D. 1 to 2 L/min via nasal cannula
Correct Answer: A
Rationale: Patients with COPD often rely on a hypoxic drive to stimulate breathing.
Delivering high concentrations of oxygen, such as 10 L/min via a non-rebreather mask, can
suppress this drive and lead to respiratory arrest. The nurse should verify any high-flow
oxygen orders to ensure patient safety and maintain appropriate CO2 levels.
2. A patient is prescribed Digoxin for heart failure. Before administration, which action is
most critical for the Practical Nurse to perform?
A. Check the patient’s blood pressure in both arms
,B. Monitor the patient’s respiratory rate
C. Auscultate the apical pulse for one full minute
D. Assess the patient for peripheral edema
Correct Answer: C
Rationale: Digoxin is a cardiac glycoside that slows the heart rate while increasing
contractility. The nurse must auscultate the apical pulse for a full 60 seconds to ensure the
heart rate is at least 60 beats per minute. If the heart rate is below 60, the medication
should be withheld and the provider notified to prevent toxicity.
3. Using the Rule of Nines, calculate the percentage of total body surface area (TBSA) burned
for an adult with burns on the entire right arm and the entire front of the torso.
A. 27%
B. 18%
C. 36%
D. 45%
Correct Answer: A
Rationale: According to the Rule of Nines, the entire arm accounts for 9% of the TBSA. The
anterior torso (chest and abdomen) accounts for 18% of the TBSA. Adding 9% and 18%
results in a total of 27% TBSA burned for this patient.
, 4. A patient is admitted with a suspected diagnosis of active pulmonary tuberculosis (TB).
Which infection control precaution is the priority?
A. Placing the patient in a negative pressure room
B. Wearing a surgical mask when entering the room
C. Limiting the patient to liquid diet only
D. Keeping the door open for better ventilation
Correct Answer: A
Rationale: Tuberculosis is transmitted through airborne droplets and requires strict
airborne precautions. This includes placing the patient in a private room with negative
pressure airflow to prevent the spread of bacteria. Healthcare workers must also wear an
N95 respirator mask rather than a standard surgical mask.
5. Which laboratory value should the nurse monitor most closely for a patient receiving
Furosemide (Lasix)?
A. Serum Sodium
B. Serum Calcium
C. Serum Potassium
D. Blood Urea Nitrogen (BUN)
Correct Answer: C
