When administering a blood transfusion to a client with multiple traumatic injuries, the nurse monitors closely for evidence of a transfusion reaction. Shortly after the transfusion begins, the client complains of chest pain, nausea and itching. When urticarial, tachycardia, and hypotension develop, the nurse stops the transfusion and notifies the physician. The nurse suspects which type of hypersensitivity reaction?

Question 1 of 9

When administering a blood transfusion to a client with multiple traumatic injuries, the nurse monitors closely for evidence of a transfusion reaction. Shortly after the transfusion begins, the client complains of chest pain, nausea and itching. When urticarial, tachycardia, and hypotension develop, the nurse stops the transfusion and notifies the physician. The nurse suspects which type of hypersensitivity reaction?

Correct Answer: A

Rationale: The correct answer is A: Type I (immediate, anaphylactic) hypersensitivity reaction. In this scenario, the client experiences symptoms shortly after the transfusion starts, such as chest pain, nausea, itching, urticaria, tachycardia, and hypotension, which are indicative of an immediate hypersensitivity reaction. Type I reactions involve the release of histamine and other inflammatory mediators from mast cells and basophils, leading to the symptoms described. The nurse's prompt action of stopping the transfusion and notifying the physician aligns with managing this type of reaction. Incorrect choices: B: Type II (cytolytic, cytotoxic) hypersensitivity reaction - This type of reaction involves antibodies targeting specific cells, leading to their destruction. The symptoms described in the scenario are not consistent with this type of reaction. C: Type III (immune complex) hypersensitivity reaction - This type of reaction involves the formation of immune complexes that deposit in tissues, causing

Question 2 of 9

Mrs. Tan is scheduled to undergo percutaneous transluminal coronary angioplasty (PTCA). Which of the following is the priority goal for her immediately after the procedure?

Correct Answer: B

Rationale: The correct answer is B: maintain blood pressure control. After PTCA, the priority goal is to ensure stable hemodynamics. Maintaining blood pressure control is crucial to prevent complications such as bleeding or thrombosis. Choices A, C, and D are incorrect because preventing fluid volume deficit, decreasing myocardial contractility, and minimizing dyspnea are not immediate priorities post-PTCA. Oxygenation and hemodynamic stability take precedence over these concerns.

Question 3 of 9

Which statement by a nurse indicates a good understanding about the differences between data validation and data interpretation?

Correct Answer: C

Rationale: The correct answer is C because data validation involves comparing data with other sources to ensure accuracy. This process helps in identifying any discrepancies or errors in the data. By cross-referencing with other sources, the nurse can verify the correctness of the data. Rationale: 1. Data validation checks the accuracy of the data by comparing it with external sources. 2. Data interpretation involves analyzing and making sense of the data, not comparing it with other sources. 3. Option A is incorrect because data validation typically comes after data collection and precedes data interpretation. 4. Option B is incorrect as validation does not specifically involve looking for patterns in professional standards. 5. Option D is incorrect because data interpretation focuses on understanding trends and insights from the data, not patterns in professional standards.

Question 4 of 9

Which of the following examples of client data needs to be validated?

Correct Answer: A

Rationale: The correct answer is A because validating the client's statement about not needing glasses is crucial for accurate data collection. This step ensures that the client's difficulty reading is not due to poor eyesight. - Choice B is about interpreting physical signs, not client data validation. - Choice C involves documenting objective findings, not validating client information. - Choice D pertains to a client's complaint, not necessarily requiring validation.

Question 5 of 9

Which of the following measures will not help correct the patient’s condition

Correct Answer: C

Rationale: Step-by-step rationale: 1. Providing oral care does not directly address fluid balance or hydration status. 2. Oral care focuses on maintaining oral hygiene and preventing infections. 3. Choices A, B, and D all involve fluid intake to address dehydration. 4. Offering large amounts of fluid, enteral or parenteral fluids, and small volumes at frequent intervals all aim to correct the patient's condition by replenishing lost fluids. Summary: Choice C is incorrect because oral care does not directly address the patient's dehydration. Choices A, B, and D are better options as they focus on fluid replacement to correct the patient's condition.

Question 6 of 9

The adrenal cortex is responsible for producing which substances?

Correct Answer: A

Rationale: The correct answer is A: Glucocorticoids and androgens. The adrenal cortex is divided into three layers, with the outer layer responsible for producing mineralocorticoids like aldosterone, the middle layer producing glucocorticoids like cortisol, and the inner layer producing androgens. Glucocorticoids are essential for regulating metabolism and immune response, while androgens are male sex hormones. Choices B, C, and D are incorrect because mineralocorticoids, catecholamines, norepinephrine, and epinephrine are produced by different parts of the adrenal gland, not specifically by the adrenal cortex.

Question 7 of 9

Which of the following patients should the nurse monitors because of increased risk for surgical complications?

Correct Answer: B

Rationale: The correct answer is B because the patient's Body Mass Index (BMI) indicates obesity, putting them at higher risk for surgical complications. Obesity is associated with increased risks of infections, delayed wound healing, respiratory issues, and cardiovascular problems post-surgery. Monitoring this patient closely is crucial. Choice A is less likely to have increased surgical complications due to age and condition. Choice C, a 12-year-old, is less likely to have significant surgical complications compared to adults. Choice D, a 17-year-old with gallstones, may have risks but the BMI of the patient in choice B indicates a higher risk.

Question 8 of 9

A client is admitted for postoperative assessment and recovery after surgery for a kidney tumor. The nurse needs to assess for signs of urinary tract infection. Which of the ff measures can be used to help detect UTI?

Correct Answer: B

Rationale: The correct answer is B: Monitor temperature every 4hrs. This is crucial in detecting signs of urinary tract infection as fever is a common symptom. Monitoring temperature regularly allows for early detection and appropriate intervention. A: Encouraging the client to breathe deeply and cough every 2hrs is a measure to prevent respiratory complications postoperatively, not related to UTI detection. C: Splinting the incision when repositioning the client is important for wound care, not for detecting UTI. D: Irrigating tubes as ordered is a specific intervention for tube care, not for monitoring UTI symptoms.

Question 9 of 9

A client undergoes a biopsy of a suspicious lesion. The biopsy report classifies the lesion according to the TNM staging system as follows: TIS, NO, MO. What does this classification mean?

Correct Answer: B

Rationale: Step 1: TIS stands for carcinoma in situ, which means cancer cells are present only in the layer of cells where they first developed. Step 2: N0 indicates no abnormal regional lymph nodes are involved. Step 3: M0 signifies no evidence of distant metastasis. Therefore, the correct answer is B because it accurately interprets the TNM staging system for the biopsy report. Summary: A: Incorrect - TIS indicates carcinoma in situ, not no evidence of primary tumor. C: Incorrect - TIS already assesses tumor presence, ruling out this option. D: Incorrect - TIS is not about ascending degrees of distant metastasis.
