1. What action should you take if a newborn's heart rate is 50 beats/min?

• A. Begin chest compressions.
• B. Reassess in 30 seconds.
• C. Administer blow-by oxygen.
• D. Start positive-pressure ventilations.

Correct answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

2. When assessing a geriatric patient who has possibly experienced an acute ischemic stroke, which of the following questions would be MOST appropriate to ask?

• A. When did you first notice the symptoms?
• B. Do you have a history of high blood pressure?
• C. What medications do you take and why?
• D. Have you previously had a heart attack?

Correct answer: A

Rationale: The most appropriate question to ask when assessing a geriatric patient who may have experienced an acute ischemic stroke is when the symptoms were first noticed. This information is crucial for determining the time window for potential treatments like thrombolytic therapy, as prompt intervention is necessary for stroke management. Option B is not as relevant in the acute assessment of stroke, though important for overall health history. Option C is important but may not be as time-sensitive as determining symptom onset. Option D focuses on a different cardiac event, not directly related to the current concern of a possible stroke.

3. What comment made by a parent of a 1-month-old would alert the nurse about the presence of a congenital heart defect?

• A. He is always hungry.
• B. He tires out during feedings.
• C. He is fussy for several hours every day.
• D. He sleeps all the time.

Correct answer: B

Rationale: Observing a 1-month-old tiring out during feedings should alert the nurse to the possibility of a congenital heart defect. This symptom may indicate that the infant is expending excess energy to compensate for a heart issue, leading to fatigue during feeding. Choices A, C, and D do not directly relate to a congenital heart defect. Being always hungry, fussy, or sleeping a lot are not specific signs of a congenital heart defect in a 1-month-old.

4. Which of the following is the MOST detrimental effect of gastric distention in infants and children?

• A. Tracheal rupture.
• B. Less effective chest compressions.
• C. Decreased ventilatory volume.
• D. Acute rupture of the diaphragm.

Correct answer: C

Rationale: Gastric distention in infants and children can lead to a decrease in ventilatory volume. This occurs because the distended stomach can limit the movement of the diaphragm, reducing its ability to contract and expand the chest cavity effectively. As a result, the amount of air entering and leaving the lungs is decreased, impacting ventilation. Tracheal rupture, acute rupture of the diaphragm, and less effective chest compressions are not typically associated with gastric distention.

5. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse'. Hormones communicate this effect by their unique chemical structures recognized by specific receptors on their target cells, by their patterns of secretion, and their concentrations in the general or local circulation. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct answer: A

Rationale: The function of producing new offspring is not attributed to hormones. Hormones primarily regulate various physiological processes in the body such as growth, metabolism, reproduction, and immune response, but they do not directly play a role in producing offspring.
