The practical nurse (PN) is auscultating a client's heart sounds. Which abnormal heart sound should the PN report to the charge nurse? (Please listen to the audio file to select the option that applies.)
S4.
S2.
S1.
S3.
Correct Answer : A,D
S3 is an extra heart sound that occurs during diastole (the filling phase of the cardiac cycle). It is commonly associated with conditions such as heart failure and volume overload. S3 is often described as a low-frequency, dull, and distant sound heard after S2 (the second heart sound).
B, C- S1, and S2 are the normal heart sounds that are typically heard in all individuals. S1 is the first heart sound, heard as "lub," and is caused by the closure of the mitral and tricuspid valves. S2 is the second heart sound, heard as "dub," and is caused by the closure of the aortic and pulmonic valves. These sounds are normal and expected.
S4 is another abnormal heart sound, which occurs during late diastole and is associated with conditions such as ventricular hypertrophy and reduced ventricular compliance.

Correct Answer is D, C, A, B
Explanation
- A 12-year-old child with a history of asthma is wheezing and complaining of shortness of breath. Wheezing and shortness of breath indicate respiratory distress, which can be a medical emergency for a child with asthma. Prompt intervention and assessment of the child's respiratory status are crucial.
- A 7-year-old child who has type 1 diabetes mellitus is experiencing extreme hunger and shakiness. These symptoms may indicate hypoglycemia, which requires immediate attention to prevent further complications. The PN should assess the child's blood glucose levels and provide appropriate treatment.
- A 10-year-old child with bleeding lacerations on both knees after falling on the playground. While bleeding lacerations require attention, they are not immediately life-threatening or likely to cause severe complications. However, the PN should still address this child's injuries promptly and provide appropriate wound care.
- A 5-year-old child is crying uncontrollably because of an incontinent bowel episode. While the child's distress is significant, it does not indicate an immediate life-threatening condition or urgent medical need. The PN should provide comfort, and reassurance, and assist with appropriate hygiene measures for the child.
Prioritizing care in this order ensures that the most urgent and potentially life-threatening conditions are addressed first, followed by those requiring immediate attention but with a lower risk of complications. Finally, the PN can attend to the client with a condition that, while distressing, is not immediately life-threatening or urgent.
Correct Answer is B
Explanation
While all of the options address the issue of impaired mobility related to fear of falling, the desired outcome of ambulating with assistance q4 hours is the most specific and measurable goal. This outcome focuses on promoting mobility and addressing the client's fear of falling by providing the necessary assistance during ambulation. It ensures that the client is engaging in regular activity and working towards regaining mobility.
The other options address different aspects of the nursing problem:
A. "The client will use self-affirmation statements to decrease fear" is a potential intervention that can be used to address the client's fear of falling, but it does not directly address the issue of impaired mobility.
C. "The physical therapist will instruct the client in the use of a walker" is an intervention that can be helpful in improving mobility, but it does not specify the frequency or timing of ambulation.
D. "The PN will place a gait belt on the client prior to ambulation" is a specific intervention that ensures the safety of the client during ambulation, but it does not address the frequency or timing of ambulation.
