A nurse is preparing to measure an infant's vital signs. The nurse should use which of the following sites to assess a heart rate?
Brachial artery
Radial artery
Apex of the heart
Carotid artery
The Correct Answer is A
Rationale:
A. The brachial artery is commonly used to assess the heart rate in infants due to its accessibility and the ease of palpation in smaller limbs.
B. The radial artery is not typically used in infants because it is less accessible and not as easily palpated in this age group.
C. While the apex of the heart is where heart sounds are best auscultated, it is not used to palpate the pulse in infants.
D. The carotid artery is not typically used for assessing the heart rate in infants due to the risk of applying excessive pressure.

Correct Answer is ["B","D","E","H"]
Explanation
Rationale:
A. While the child’s oral intake is reduced, it is not as immediately critical as the other findings. However, it should still be monitored and managed.
B. The child’s blood pressure has dropped to 88/48 mm Hg on Day 3, which is significantly lower than the initial value and may indicate hypotension. This could be a sign of worsening condition or dehydration and needs to be reported for further evaluation and intervention.
C. The temperature of 38.1° C (100.6° F) on Day 3 indicates a fever but is lower than the initial admission temperature. It is important but not as critical as the other findings in this scenario.
D. The oxygen saturation has decreased to 88% on room air, which is below the normal range and indicates hypoxemia. This is critical in a patient with pneumonia and cystic fibrosis, and it requires immediate attention to manage respiratory function and oxygenation.
E. The child has passed three large, frothy, foul-smelling stools, which could be indicative of a gastrointestinal complication, possibly related to cystic fibrosis. This change in bowel habits should be reported as it may impact the child’s overall condition and treatment plan.
F. The sputum is thick, yellow, and blood-streaked, which is consistent with the condition but does not require immediate reporting unless there is a significant change in color or consistency.
G. The reported pain level of 4 on a scale of 0 to 10 is moderate but not life-threatening. It should be managed, but it is less urgent compared to other assessment findings.
H. The child is using accessory muscles for respiration and is experiencing dyspnea while at rest, which suggests worsening respiratory distress. This is crucial to report as it reflects the severity of the pneumonia and may need adjustments in the treatment plan.
Correct Answer is A
Explanation
Rationale:
A. When mixing insulins, the short-acting insulin should be drawn into the syringe first to avoid contamination of the short-acting insulin with the long-acting insulin.
B. Insulin should be administered subcutaneously, not intramuscularly, and the sites should be rotated to avoid lipodystrophy.
C. Insulin should be administered at a 90-degree angle, not 30 degrees, to ensure proper subcutaneous delivery.
D. Wiping the needle with an alcohol swab is unnecessary and could introduce contaminants.
