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 ["A","E"]
Explanation
A. This is a client care intervention that the PN can assign to the UAP. Transporting a urine culture sample to the laboratory is a routine and non-invasive task that does not require clinical judgment or skill. The UAP should follow the standard precautions and protocols for handling and labeling the specimen.
E. This is a client care intervention that the PN can assign to the UAP. Emptying the bedside drainage unit for a client with an indwelling urinary catheter is a routine and non-invasive task that does not require clinical judgment or skill. The UAP should follow the standard precautions and protocols for emptying, measuring, and recording the urine output.
B. This is not a client care intervention that the PN can assign to the UAP. Obtaining a post-voided residual (PVR) volume is a procedure that requires clinical judgment and skill, as it involves using a bladder scanner or catheterizing the client to measure the amount of urine left in the bladder after voiding. The UAP is not trained or authorized to perform this task, and it should be done by the PN or another licensed nurse.
C.This is not a client care intervention that the PN can assign to the UAP. Teaching the client with fluid restrictions how to measure urine output is an educational activity that requires clinical judgment and skill, as it involves assessing the client's learning needs, providing clear and accurate instructions, and evaluating the client's understanding and compliance. The UAP is not trained or authorized to perform this task, and it should be done by the PN or another licensed nurse.
D.This is not a client care intervention that the PN can assign to the UAP. Irrigating an indwelling urinary catheter for a client with bladder suspension is a procedure that requires clinical judgment and skill, as it involves inserting sterile fluid into the bladder through the catheter to flush out any clots, debris, or bacteria. The UAP is not trained or authorized to perform this task, and it should be done by the PN or another licensed nurse.
Correct Answer is ["0.75"]
Explanation
To calculate the volume of medication to administer, we can use the following conversion: 1 mg = 1000 mcg
Given that the prescribed dose is 150 mcg/day, we need to convert it to milligrams: 150 mcg = 150/1000 mg = 0.15 mg
Since the medication is available in 0.2 mg/mL vials, we can calculate the volume to administer using the following equation:
Volume (mL) = Dose (mg) / Concentration (mg/mL) Volume (mL) = 0.15 mg / 0.2 mg/mL
Volume (mL) = 0.75 mL
Therefore, the practical nurse (PN) should administer 0.75 mL of the medication.
