LPN Fundamentals Questions Questions
Question 1 of 5
Which of the following cells of the body are in almost constant mitosis?
Correct Answer: B
Rationale: Stomach cells undergo constant mitosis to replace lining lost to digestion, unlike nerve cells (rarely divide), muscle (slow turnover), or renal cells (less frequent). This informs nursing care, like monitoring gastric healing in ulcers.
Question 2 of 5
The newborn infant's stomach capacity is approximately which of the following in milliliters?
Correct Answer: B
Rationale: A newborn's stomach holds about 90 mL, fitting early feeding needs, unlike other volumes. Nurses use this for feeding plans.
Question 3 of 5
What is the primary purpose of using a drawsheet during patient repositioning?
Correct Answer: B
Rationale: Using a drawsheet primarily facilitates mechanical lift use during repositioning, aiding smooth patient sliding and transfer while enhancing safety for both patient and caregiver. It may reduce shear-related ulcers or improve comfort, but these are secondary, and caregiver protection isn't the main aim. Nurses rely on this to streamline lift-assisted moves, ensuring efficiency and safety in handling immobile patients, a practical application in daily care.
Question 4 of 5
A client with acute respiratory distress syndrome (ARDS) requires high levels of positive end-expiratory pressure (PEEP). Which oxygen delivery system would be most effective in providing the necessary PEEP?
Correct Answer: C
Rationale: A CPAP mask (C) effectively delivers PEEP in ARDS, maintaining airway pressure to improve oxygenation. Non-rebreather (A) and Venturi (B) don't provide PEEP. BVM (D) is for resuscitation, not continuous PEEP. CPAP supports alveolar recruitment, per critical care standards, vital in ARDS management.
Question 5 of 5
A client receiving HydroDIURIL (hydrochlorothiazide) is instructed to increase her dietary intake of potassium. The best snack for the client requiring increased potassium is:
Correct Answer: D
Rationale: Hydrochlorothiazide, a diuretic, increases potassium excretion, necessitating dietary potassium boosts to prevent hypokalemia, which can cause muscle weakness or arrhythmias. Among the options, bananas are renowned for high potassium content about 400-450 mg per medium fruit far exceeding pears (around 190 mg), apples (about 150 mg), or oranges (approximately 230 mg). This makes bananas the optimal snack to replenish potassium effectively, aligning with the client's therapeutic needs. Nurses educate clients on such choices to maintain electrolyte balance, emphasizing potassium-rich foods to counteract medication side effects and support overall health.
