Fundamentals HESI

Correct Answer: A

Rationale: The correct answer is to infuse hypotonic IV fluids. In hypernatremia, there is an elevated sodium concentration in the blood, and diluting it with hypotonic fluids helps to lower the sodium levels. Implementing a fluid restriction or increasing sodium intake would worsen hypernatremia by further concentrating sodium in the body. Administering sodium polystyrene sulfonate is used for treating hyperkalemia, not hypernatremia.

Correct Answer: B

Rationale: A new or changed heart murmur is a common sign of valve involvement in infective endocarditis, indicating a complication such as valve damage or regurgitation. Dyspnea is more commonly associated with respiratory or cardiac conditions not directly related to infective endocarditis. A macular rash is not a typical symptom of infective endocarditis, suggesting other conditions like infectious diseases. Hemorrhage is not a direct complication of infective endocarditis but may occur due to factors such as anticoagulant therapy or underlying bleeding disorders.

Correct Answer: A

Rationale: The correct sequence for an abdominal assessment in an adult client is to first Inspect the abdomen for any visible abnormalities, then Auscultate to listen for bowel sounds, followed by Percussion to assess for organ size and presence of fluid or masses, and finally Palpation to feel for tenderness, masses, or organ enlargement. Choice A, 'Inspect, Auscultate, Percuss, Palpate,' is the correct sequence for an abdominal assessment. Choices B, C, and D are incorrect because they do not follow the recommended sequence of assessment. Palpation should be the last step as it can potentially alter bowel sounds and percussion findings if done before. This deviation can lead to missing important findings or inaccurate assessment results.

Correct Answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

Correct Answer: D

Rationale: When assessing the way a patient walks, the healthcare provider is evaluating the gait, which refers to a particular manner or style of walking. Body alignment pertains to the positioning of body parts in relation to one another, range of motion refers to the extent of movement of a joint, and activity tolerance relates to the ability to endure physical activities. In this scenario, observing the patient's walking pattern specifically focuses on gait assessment.
