1. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.

2. A caregiver is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The caregiver asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the caregiver make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.

3. According to the principles of standard precautions, when should gloves be worn by healthcare providers?

• A. Providing a back massage
• B. Feeding a client
• C. Providing hair care
• D. Providing oral hygiene

Correct answer: D

Rationale: Gloves should be worn when providing oral hygiene as it involves potential exposure to bodily fluids, aligning with the standard precautions to prevent the transmission of infections. Providing a back massage, feeding a client, and providing hair care do not typically involve direct exposure to bodily fluids, so wearing gloves is not necessary in these scenarios according to standard precautions.

4. After 5 days of diuretic therapy with 20mg of furosemide (Lasix) daily, a patient begins to exhibit fatigue, muscle cramping, and muscle weakness. These symptoms probably indicate that the patient is experiencing:

• A. Hypokalemia
• B. Hyperkalemia
• C. Anorexia
• D. Dysphagia

Correct answer: A

Rationale: The symptoms of fatigue, muscle cramping, and muscle weakness in a patient after starting furosemide therapy are indicative of hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion, causing hypokalemia. Hypokalemia can manifest with muscle weakness, cramps, and fatigue due to alterations in neuromuscular function and decreased ATP production.

5. A healthcare professional is preparing to assess a 2-week-old newborn. Which of the following actions should the professional plan to take?

• A. Obtain the newborn's body temperature using a tympanic thermometer.
• B. FACES pain scale.
• C. Auscultate the newborn's apical pulse for 60 seconds.
• D. Measure the newborn's head circumference over the eyebrows and below the occipital prominence.

Correct answer: C

Rationale: Assessing the apical pulse in newborns is important to evaluate their cardiac function. The normal heart rate for a newborn is typically between 100-160 beats per minute. Auscultating the apical pulse for a full 60 seconds allows for an accurate assessment of the newborn's heart rate. This is a crucial component of the newborn assessment to ensure the baby's cardiovascular system is functioning within the expected range.
