A nurse is caring for a 2-month-old infant who has heart failure.
Which of the following actions should the nurse take?
Limit oral feedings to 30 min in length.
Weigh the infant every other day.
Place the infant in the prone position for naps.
Check the infant’s oxygen saturation every 6 hr.
undefined
The Correct Answer is A
The correct answer is choice A. Limit oral feedings to 30 min in length.
This is because infants with heart failure have difficulty feeding and may become exhausted or dyspneic during prolonged feedings. By limiting the feeding time, the nurse can reduce the energy expenditure and caloric needs of the infant.
Choice B is wrong because weighing the infant every other day is not enough to monitor the fluid status and nutritional intake of the infant. The nurse should weigh the infant daily at the same time using the same scale.
Choice C is wrong because placing the infant in the prone position can compromise the respiratory function and increase the risk of sudden infant death syndrome (SIDS). The nurse should place the infant in a semi-Fowler’s position to facilitate breathing and decrease venous return.
Choice D is wrong because checking the infant’s oxygen saturation every 6 hr is not frequent enough to detect hypoxia or cyanosis. The nurse should monitor the oxygen saturation continuously or at least every 2 hr.

Correct Answer is C
Explanation
The correct answer is C. Explain to the child what will happen when the abuse is reported.
This is because the nurse should provide honest and accurate information to the child about the reporting process and the possible outcomes, such as legal actions, investigations, or removal from the home.
This can help the child feel more prepared and less anxious about what will happen next. The nurse should also reassure the child that the abuse is not their fault and that they did the right thing by telling someone.
Choice A is wrong because reassuring the child that no one will be told about the abuse is unethical and illegal.
The nurse has a mandatory duty to report any suspected or confirmed cases of child abuse to the appropriate authorities, such as child protective services or law enforcement. Keeping the abuse a secret can also endanger the child’s safety and well-being, as well as prevent them from receiving the necessary medical and psychological care.
Choice B is wrong because ensuring that multiple nurses are present for the physical examination can increase the child’s fear, embarrassment, or discomfort.
The nurse should minimize the number of people involved in the examination and only include those who are essential for providing care or collecting evidence. The nurse should also explain to the child what will be done during the examination and obtain their consent before proceeding.
Choice D is wrong because using leading statements to obtain information from the child can influence their responses and affect the validity of their testimony.
The nurse should use open-ended questions and avoid suggesting or implying any details about the abuse. The nurse should also document the child’s statements verbatim and avoid interpreting or paraphrasing them.
Correct Answer is C
Explanation
- . Answer and explanation.
The correct answer is choice C, first-degree atrioventricular block.
This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip.
In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.
Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.
There is no constant PR interval in atrial fibrillation.
Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.
There are no consistent P waves or PR intervals in complete heart block.
Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.
They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.
However, they do not cause a constant prolongation of the PR interval.
