Free Master of Science in Nursing MCQ Questions and Answers — Questions and Answers
Question 1: What's a healthy adult male's approximate total lung capacity?
- 6000 L (Correct answer)
- 500 mL
- 5000 L
- 6000 mL
Correct answer: 6000 L
A healthy adult male's approximate total lung capacity (TLC) is around 6000 mL, which is equivalent to 6 liters. This represents the maximum amount of air the lungs can hold after a maximal inspiration. The option '6000 L' would be an impossibly large volume, making '6000 mL' the correct physiological answer.
Question 2: The best way to apply roller bandages to body areas with different thicknesses, such the forearm, is?
- Figure of eight
- Reverse spiral (Correct answer)
- Divergent Spica
- Simple spiral
Correct answer: Reverse spiral
The reverse spiral bandage technique is ideal for bandaging body parts that vary significantly in circumference, such as the forearm or lower leg. This method involves folding the bandage back on itself at an angle with each turn, allowing it to conform smoothly to the changing contours of the limb. It provides even pressure and prevents gaps or looseness.
Question 3: Using prevents the external rotation of the hip when in the supine posture.
- Knee rest
- Bed cradle
- Bedboard
- Trochanter roll (Correct answer)
Correct answer: Trochanter roll
A trochanter roll is a supportive device, typically a rolled blanket or towel, placed alongside a patient's hips and thighs when they are in the supine position. Its primary purpose is to prevent external rotation of the hips and maintain proper alignment of the lower extremities. This helps prevent complications like hip contractures.
Question 4: The Trendelenburg position is used to drain secretions during postural drainage.
- Lateral segment of right lower lobe
- Lateral segment of the left lower lobe
- Anterior segment of both lower lobes of lungs (Correct answer)
- Posterior segment of both lower lobes of lungs
Correct answer: Anterior segment of both lower lobes of lungs
The Trendelenburg position, where the patient lies supine with the head lower than the feet, is used in postural drainage to facilitate the drainage of secretions from specific lung segments. For the anterior segments of both lower lobes, this position allows gravity to help move mucus towards the larger airways for expectoration. This aids in clearing the lungs and improving respiratory function.
Question 5: What is a quick and affordable technique for lowering the risk of hypostatic pneumonia in a bedridden patient?
- Humidified oxygen
- Antibiotics
- Nebulization
- Frequent change of positions (Correct answer)
Correct answer: Frequent change of positions
Frequent repositioning of a bedridden patient is a simple, affordable, and highly effective intervention to lower the risk of hypostatic pneumonia. Changing positions helps to mobilize respiratory secretions, promote lung expansion, and improve ventilation and perfusion in different areas of the lungs. This prevents fluid accumulation and reduces the likelihood of infection.
Question 6: The nurse should be aware of this when moving a patient with intercostal drainage (ICD) tubes.
- Do not clamp the chest tube and keep the drainage system below the chest (Correct answer)
- Do not clamp the chest tube and keep the drainage system on the trolley
- Clamp the chest tube and keep the drainage system below the chest
- Clamp the chest tube and keep the drainage system on the trolley
Correct answer: Do not clamp the chest tube and keep the drainage system below the chest
When moving a patient with intercostal drainage (ICD) tubes, it is crucial not to clamp the chest tube unless specifically ordered or in an emergency, as clamping can lead to tension pneumothorax. Additionally, the drainage system must always be kept below the level of the patient's chest to ensure proper gravity drainage and prevent backflow of fluid into the pleural space. This maintains the integrity of the closed drainage system.
Question 7: Which of the following is an illustration of an intravenous isotonic solution?
- 0.45% NaCl
- Ringer’s Lactate (Correct answer)
- Dextrose normal saline
- 10% Dextrose
Correct answer: Ringer’s Lactate
Ringer’s Lactate (RL) is an intravenous isotonic solution, meaning it has an osmolality similar to that of blood plasma. This characteristic allows it to expand the intravascular fluid volume without causing significant fluid shifts between intracellular and extracellular compartments. It is commonly used for fluid resuscitation and electrolyte replacement.
