A nurse is assessing a client who has full-thickness burns. The nurse should identify that which of the following findings indicates the client's need for fluid resuscitation?

Rationale:

A. "Initiate venous access with a 21-gauge needle." For blood transfusions, it is recommended to use a larger gauge needle, 18-20 gauge, to allow for proper blood flow and reduce the risk of hemolysis. A 21-gauge needle is too small for optimal transfusion.

B. "Obtain the client's first set of vital signs 1 hr after initiating the transfusion." The first set of vital signs should be obtained immediately before starting the transfusion, and then monitored every 15 minutes to detect any early signs of a transfusion reaction.

C. "Administer the unit of packed RBCs over 1 hr." The unit of packed RBCs should be administered over 4 hours to reduce the risk of transfusion reactions and allow for optimal oxygen-carrying capacity. Infusing blood too quickly can cause complications such as volume overload or reactions.

D. "Use Y tubing with 0.9% sodium chloride when administering the transfusion." Y tubing is commonly used for blood transfusions to allow for the infusion of normal saline (0.9% sodium chloride) alongside the blood product. This helps maintain the flow of the transfusion and reduces the risk of clot formation while flushing the line.

Rationale for Correct Choices:

• Left-sided heart failure: The client’s symptoms of dyspnea, fatigue with activity, heart palpitations, coughing at night, and bilateral crackles in the lung bases indicate left-sided heart failure. The fluid buildup in the lungs is a key feature of left-sided heart failure, causing symptoms like difficulty breathing and crackles on auscultation.
• Administer a loop diuretic: Loop diuretics, like furosemide, help reduce fluid buildup in the lungs and peripheral tissues by increasing urine output. This is essential in left-sided heart failure, where fluid retention leads to symptoms such as dyspnea and crackles.
• Administer morphine IV: Morphine is used in acute heart failure to relieve pain and anxiety, as well as to reduce preload and afterload. It helps to dilate blood vessels and can improve breathing by reducing the workload on the heart.
• Lung sounds: Crackles in the bases of the lungs are indicative of fluid accumulation due to left-sided heart failure. Improvement or worsening of these crackles will indicate the effectiveness of the diuretic therapy and other interventions.
• Pulse strength: Weak pulses (+1) may indicate poor perfusion due to heart failure. Monitoring changes in pulse strength can guide the nurse in assessing the client’s circulatory status and the response to treatment.

Rationale for Incorrect Choices:

• Prepare the client for a valvuloplasty: Valvuloplasty is indicated for patients with valvular heart disease, typically involving the mitral or aortic valve. This client’s symptoms and diagnostic results suggest left-sided heart failure rather than a primary valve problem.
• Obtain the client's temperature: The client's temperature (37.2°C) is within normal limits and does not indicate any fever or infection. Temperature monitoring is not a priority at this moment.
• Assess the client's abdomen: Although abdominal distention and ascites are common in right-sided heart failure, the client's symptoms (dyspnea, crackles, and fatigue) are more indicative of left-sided heart failure. Abdominal assessment is not as critical in this scenario.
• Mitral valve prolapse: Mitral valve prolapse often presents with palpitations, chest pain, and sometimes murmur, but it does not typically cause the same degree of fluid buildup and symptoms (dyspnea and crackles) as left-sided heart failure as seen in this patient.
• Right-sided heart failure: This client's presentation is more consistent with left-sided heart failure. The primary symptoms of left-sided heart failure (dyspnea, fatigue, crackles, and lung congestion) are present, and no signs of right-sided heart failure (like edema or jugular venous distension) are noted.
• Infective endocarditis: Infective endocarditis usually presents with fever, heart murmurs, and signs of infection, which are not evident in this case. The client’s symptoms suggest heart failure rather than an infectious process.
• Heart sounds for systolic murmur: The heart sounds are noted as "clear" with an irregular rhythm, suggesting an arrhythmia rather than a structural heart problem that would typically cause a systolic murmur.
• Blood culture results: Blood cultures would be necessary if there was a suspected infection, such as infective endocarditis, but there is no indication of infection in this client. The primary concern is heart failure, so blood cultures are not needed at this time.
• Liver function tests: Liver function tests may be useful in cases of right-sided heart failure where hepatic congestion is common, but in left-sided heart failure, the priority is managing fluid retention and improving oxygenation.
