A nurse is performing a cardiac assessment on a client and auscultates an S3 sound. The nurse should recognize that this sound represents which of the following heart conditions?
Closure of pulmonic valve
Closure of the mitral valve
Ventricular gallop
Atrial gallop
The Correct Answer is C
Ventricular gallop is another name for the S3 sound, which is a low-pitched sound heard at the end of diastole, just after the S2 sound. It is caused by the rapid filling of the ventricles and the vibration of the ventricular walls.
Closure of the pulmonic valve is one of the components of the S2 sound, which is a high-pitched sound heard at the end of the systole, just before the S1 sound. It is caused by the closure of the semilunar valves (pulmonic and aortic).
Closure of the mitral valve is one of the components of the S1 sound, which is a high-pitched sound heard at the beginning of systole, just after the S2 sound. It is caused by the closure of the atrioventricular valves (mitral and tricuspid).
d. Atrial gallop is another name for the S4 sound, which is a low-pitched sound heard at the end of diastole, just before the S1 sound. It is caused by atrial contraction and increased resistance to ventricular filling.

Correct Answer is B
Explanation
A. Using simple language is helpful, but speaking in a childlike manner can be demeaning and may lower the client’s self-esteem. Communication should remain respectful and age-appropriate.
B. Incorporating nonverbal cues such as gestures, facial expressions, pictures, and written words supports understanding. Clients with aphasia often benefit from visual aids and other alternative communication strategies to enhance comprehension.
C. Raising the pitch of the voice does not improve comprehension in aphasia because the issue is related to language processing rather than hearing ability. A normal tone should be maintained unless the client has a hearing impairment.
D. Asking multiple-choice questions can sometimes assist with expressive aphasia; however, relying solely on this method may limit natural communication. The broader and more supportive approach is to incorporate nonverbal communication techniques.
Correct Answer is D
Explanation
Taking one tablet at the first indication of chest pain is the correct way to use SL nitroglycerin tablets, as they are fast- acting and can relieve anginal symptoms within minutes. The client should place the tablet under the tongue and let it dissolve.
Taking one tablet at the first indication of chest pain is the correct way to use SL nitroglycerin tablets, as they are fast- acting and can relieve anginal symptoms within minutes. The client should place the tablet under the tongue and let it dissolve.
Taking this medication after each meal and at bedtime is not appropriate, as SL nitroglycerin tablets are not meant for routine or prophylactic use, but only for acute episodes of angina.
Taking one tablet every 15 min during an acute attack is not correct, as the client should not exceed three doses in 15 min. If the pain is not relieved after three doses, the client should seek emergency medical attention.
Taking this medication with 8 ounces of water is not necessary, as SL nitroglycerin tablets do not need to be swallowed or washed down with water. They should be dissolved under the tongue for optimal absorption.
