After placing a stethoscope to auscultate S1 and S2 heart sounds, what should the nurse do to check for an S3 heart sound?
- A. Switch to the diaphragm of the stethoscope to hear any abnormal sounds
- B. Listen with the bell of the stethoscope at the same location
- C. Listen at a different location over the aortic area
- D. Switch to the apical area and reassess for S3 sounds
Correct Answer: B
Rationale: To assess for an S3 heart sound, the nurse should listen with the bell of the stethoscope. An S3 heart sound is often low-pitched and best heard with the bell. Choice A is incorrect because switching to the diaphragm is not ideal for detecting low-pitched sounds like an S3. Choice C is incorrect as the S3 heart sound is best heard over the apex of the heart, not the aortic area. Choice D is incorrect because moving to the apical area is appropriate, but the nurse should specifically use the bell of the stethoscope to listen for S3 sounds.

A client is admitted with a suspected gastrointestinal bleed. What assessment finding requires immediate intervention?
- A. Bright red blood in the vomit.
- B. Elevated blood pressure and heart rate.
- C. Coffee ground emesis.
- D. Dark, tarry stools.
Correct Answer: D
Rationale: Dark, tarry stools indicate the presence of digested blood in the gastrointestinal tract, signifying a higher gastrointestinal bleed. This finding requires immediate intervention due to the potential severity of the bleed. Bright red blood in the vomit may indicate active bleeding but is not as concerning as digested blood. Elevated blood pressure and heart rate are common responses to bleeding but do not provide direct evidence of the source or severity of the bleed. Coffee ground emesis is indicative of partially digested blood and is a concern but not as urgent as dark, tarry stools.
A nurse from the maternity unit is floated to the critical care unit because of staff shortage on the evening shift. Which client would be appropriate to assign to this nurse?
- A. A client with a Dopamine drip IV with vital signs monitored every 5 minutes
- B. A client with a myocardial infarction that is free from pain and dysrhythmias
- C. A client with a tracheotomy of 24 hours in some respiratory distress
- D. A client with a pacemaker inserted this morning with intermittent capture
Correct Answer: B
Rationale: In this scenario, it is more appropriate to assign a stable client, such as the one with a myocardial infarction who is free from pain and dysrhythmias, to a nurse who lacks specialized critical care experience. This client's condition is relatively stable and does not require immediate critical interventions. Choices A, C, and D involve clients with more complex and critical conditions that would be better managed by a nurse with specialized critical care training. Choice A involves a client on a Dopamine drip with frequent vital sign monitoring, Choice C has a client with a tracheotomy in respiratory distress, and Choice D describes a client with a pacemaker experiencing intermittent capture, all of which require a higher level of critical care expertise.
A client with heart failure is receiving furosemide. What assessment finding indicates the medication is effective?
- A. Increased urine output and weight loss.
- B. Increased heart rate and blood pressure.
- C. Decreased edema and improved peripheral pulses.
- D. Decreased shortness of breath and clear lung sounds.
Correct Answer: C
Rationale: The correct answer is C: 'Decreased edema and improved peripheral pulses.' In a client with heart failure, furosemide is a diuretic that helps reduce fluid overload. Therefore, a decrease in edema (swelling due to fluid retention) and improved peripheral pulses (indicating better circulation) are signs that the medication is effective. Choices A, B, and D are incorrect. Increased urine output and weight loss (Choice A) may indicate the diuretic effect of furosemide but do not specifically reflect its effectiveness in heart failure. Increased heart rate and blood pressure (Choice B) are not desired effects of furosemide and may suggest adverse reactions. Decreased shortness of breath and clear lung sounds (Choice D) are related to improved respiratory status and may not directly reflect the effectiveness of furosemide in addressing fluid overload.
A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?
- A. Prothrombin time (PT)
- B. International normalized ratio (INR)
- C. Activated partial thromboplastin time (aPTT)
- D. Platelet count
Correct Answer: C
Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.
During an excretory urogram, which observation made by the nurse indicates a complication?
- A. The client complains of a salty taste in the mouth when the dye is injected
- B. The client's entire body turns a bright red color
- C. The client states 'I have a feeling of getting warm.'
- D. The client gags and complains 'I am getting sick.'
Correct Answer: B
Rationale: The correct answer is B because a whole-body bright red color indicates a severe reaction to the contrast dye and must be addressed immediately. Choices A, C, and D do not indicate a severe complication during an excretory urogram. Choice A is a common side effect of the dye, choice C could be a normal sensation due to the injection, and choice D may indicate nausea which is less severe compared to a whole-body red color reaction.
