A nurse on a telemetry unit is assessing a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min and the PR interval is 0.24 seconds. The nurse should interpret this finding as which of the following cardiac rhythms?
Atrial fibrillation
First-degree AV block
Premature ventricular contraction
Sinus bradycardia
The Correct Answer is B
The correct answer is B.
Choice A reason: Atrial fibrillation is characterized by a rapid, irregular heartbeat and an absence of distinct P waves on the ECG, which is not indicated by the information provided.
Choice B reason: First-degree AV block is indicated by a prolonged PR interval without affecting the overall heart rate, aligning with the client’s PR interval of 0.24 seconds.
Choice C reason: Premature ventricular contraction would show an abnormal QRS complex on the ECG, which is not mentioned in the scenario.
Choice D reason: Sinus bradycardia is defined by a heart rate less than 60 bpm, which does not apply here as the client’s heart rate is 69/min, within the normal range of 60-100 bpm.

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

This is because coarctation of the aorta is a congenital condition where the aorta is narrow, usually in the area where the ductus arteriosus inserts. This causes a decrease in blood flow to the lower body, resulting in weak or absent pulses in the femoral arteries.
The other choices are incorrect for the following reasons:
- Choice A, frequent nosebleeds, is not a typical sign of coarctation of the aorta.
Nosebleeds can be caused by many factors, such as dry air, allergies, trauma, or bleeding disorders.
- Choice B, upper extremity hypotension, is also not a common finding in coarctation of the aorta. In fact, patients with this condition may have high blood pressure in the upper extremities due to the increased resistance of the narrowed aorta.
- Choice D, increased intracranial pressure, is not directly related to coarctation of the aorta.
Increased intracranial pressure can be caused by various conditions that affect the brain, such as head injury, stroke, infection, or tumor.
Normal ranges for blood pressure and pulse vary depending on age, sex, and health status.
However, some general guidelines are:
- Blood pressure: less than 120/80 mmHg for adults; less than 95/65 mmHg for infants.
- Pulse: 60 to 100 beats per minute for adults; 100 to 160 beats per minute for infants.
