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 ["C","E","F"]
Explanation
C.Place pillows around the bed rails to provide padding: During a tonic-clonic seizure, the client may experience uncontrolled movements and convulsions. Placing pillows around the bed rails helps prevent injury by providing padding and cushioning.
E.Increase the supplemental oxygen to 10 L/min via nasal cannula: The client's oxygen saturation is dangerously low at 40%. Increasing the supplemental oxygen to 10 L/min via nasal cannula will help improve oxygenation and prevent hypoxia.
F.Manually ventilate the client with a bag-valve-mask: Since the respiratory rate is only 4 breaths/min, the client is not adequately ventilating on their own. Manual ventilation with a bag-valve maskwill provide necessary oxygenation and ventilation support during the seizure.
The other options are not appropriate actions at this time:
- Begin chest compressions: Chest compressions are indicated if the client's heart has stopped or if they are in cardiac arrest. Since the scenario describes a seizure, the client's heart is presumed to be functioning.
- Watch the seizure activity and document the time and client movement: Although documentation is important, during an active seizure, the priority is to ensure the client's safety and provide immediate interventions. Documentation can be done after the seizure has ended.
- Stop the IV fluids: There is no indication to stop the IV fluids based on the given information. IV fluids are generally continued unless there is a specific reason to discontinue them.
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.
