Medical Surgical HESI Questions
Question 1 of 5
A young adult client, admitted to the emergency department following a motor vehicle collision, is transfused with 4 units of PRBCs. The client's pretransfusion hematocrit is 17%. Which hematocrit value should the nurse expect the client to have after all PRBCs have been transfused?
Correct Answer: D
Rationale: One unit of PRBCs typically raises the hematocrit by 3%. Since the client received 4 units, the hematocrit is expected to increase by approximately 12% (4 units x 3% per unit). Therefore, the nurse should expect the client's hematocrit to be 29% after all PRBCs have been transfused. Choices A, B, and C are incorrect as they do not account for the cumulative effect of multiple PRBC units on the hematocrit level.
Question 2 of 5
During the admission interview, an older client answers some questions inappropriately. The nurse notes that a hearing aid is in one ear. Which intervention is most helpful in assisting the client to hear the nurse's question?
Correct Answer: D
Rationale: Restating questions with clear articulation is the most helpful intervention in assisting the client to hear the nurse's question. This approach ensures that the client can better understand the question, especially if there are issues with the hearing aid. Moving to the client's other side or speaking louder into the ear with the hearing aid may not effectively address the problem of clarity in communication. Asking the client to adjust the hearing aid volume assumes that the issue lies solely with the volume, while restating questions with clear articulation can help overcome various hearing difficulties.
Question 3 of 5
A client admitted with left-sided heart failure has a heart rate of 110 beats per minute and is becoming increasingly dyspneic. Which additional assessment finding by the nurse supports the client's admitting diagnosis?
Correct Answer: B
Rationale: The correct answer is B: Crackles in the lung bases. Crackles in the lung bases are indicative of pulmonary congestion, which is a classic sign of left-sided heart failure. Left-sided heart failure leads to a backup of blood into the lungs, causing fluid leakage into the alveoli and resulting in crackles upon auscultation. Choices A, C, and D are less specific to left-sided heart failure. Jugular vein distention can be seen in right-sided heart failure, peripheral edema can be seen in both right and left-sided heart failure, and bounding peripheral pulses are more indicative of conditions like hyperthyroidism or anemia rather than specifically supporting left-sided heart failure.
Question 4 of 5
A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?
Correct Answer: B
Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.
Question 5 of 5
A client with rheumatoid arthritis has elevated serum rheumatoid factor. Which interpretation of this finding should the nurse make?
Correct Answer: B
Rationale: The correct interpretation of elevated serum rheumatoid factor in a client with rheumatoid arthritis is confirmation of the autoimmune disease process. Rheumatoid factor is a marker for autoimmune activity, thus confirming the diagnosis of rheumatoid arthritis. Choice A is incorrect as elevated rheumatoid factor does not specifically indicate spread of the disease to the kidney. Choice C is incorrect as elevated rheumatoid factor does not always represent a decline in the client's condition. Choice D is incorrect as elevated rheumatoid factor is not an indication of the onset of joint degeneration, but rather points towards autoimmune activity.
