The nurse is caring for a client who has signs and symptoms of heart failure. Which of the following diagnostic tests is appropriate to assess the patient’s heart failure?
International normalized ratio (INR)
Brain natriuric peptide (BNP)
Troponin
Creatinine
The Correct Answer is B
A. International normalized ratio (INR):
INR is a test used to monitor the effectiveness of anticoagulant therapy, particularly drugs like warfarin. It measures the time it takes for blood to clot. It's not directly related to assessing heart failure but is more associated with monitoring anticoagulation status.
B. Brain natriuretic peptide (BNP):
BNP is a peptide released by the heart in response to increased pressure and volume in the heart, often seen in heart failure. Elevated BNP levels can indicate the presence of heart failure. It's a useful diagnostic marker for heart failure.
C. Troponin:
Troponin is a protein released into the blood when there is damage to the heart muscle, usually during a heart attack. It is not specific to heart failure but is commonly used to diagnose myocardial infarction (heart attack).
D. Creatinine:
Creatinine is a waste product that comes from the normal wear and tear on muscles. While elevated creatinine levels can be seen in conditions affecting kidney function, it's not a direct marker for assessing heart failure. However, kidney function is often evaluated in conjunction with heart failure assessments.

Correct Answer is C
Explanation
A. Obtain a sputum sample:
This option is more relevant when the client is experiencing cough with sputum production, which might suggest respiratory issues. However, in the context of coughing after eating or drinking, the primary concern is likely related to the swallowing process rather than respiratory conditions.
B. Inspect the client’s tongue and mouth:
While inspecting the tongue and mouth is a good practice for assessing oral health, it may not directly address the issue of coughing after eating or drinking, which is more indicative of potential swallowing difficulties.
C. Perform a swallowing assessment:
This is the most appropriate option for the given scenario. A swallowing assessment helps identify any abnormalities or difficulties in the swallowing process, which could contribute to the client's coughing after eating or drinking.
D. Assess the client’s nutritional status:
While assessing nutritional status is important for overall health, it may not directly address the immediate concern of coughing after eating or drinking. Nutritional status assessment is a broader aspect of care.
Correct Answer is C
Explanation
A. Partial non-rebreathing mask:
This mask delivers higher concentrations of oxygen than a nasal cannula. It has a reservoir bag that allows the client to rebreathe some exhaled air, increasing the oxygen concentration delivered. However, it may not be necessary for a client with mild shortness of breath and slightly reduced oxygen saturation.
B. Simple (Oxy Plus) mask:
The simple mask provides a higher concentration of oxygen than a nasal cannula but lacks the reservoir bag found in the non-rebreathing mask. It is generally used for moderate oxygen needs. However, it might be more than what is required for a client with mild shortness of breath and slightly reduced oxygen saturation.
C. Nasal cannula:
Nasal cannulas are commonly used for clients with mild respiratory distress. They deliver a lower to moderate concentration of oxygen and are well-tolerated by most clients. They are suitable for individuals with mild shortness of breath and can be adjusted based on the required flow rate.
D. Non-rebreathing mask:
The non-rebreathing mask provides the highest concentration of oxygen among the options listed. It includes a reservoir bag to deliver a higher oxygen concentration. It is typically reserved for clients with higher oxygen requirements. For a client with mild shortness of breath and slightly reduced oxygen saturation, this may be more than necessary.
