Adult Health Exam 1 Chamberlain
1. A client with a history of hypertension is admitted to the hospital for a suspected myocardial infarction. Which of the following is the priority nursing action?
- A. Administer oxygen as prescribed
- B. Perform an ECG
- C. Obtain a detailed health history
- D. Monitor vital signs regularly
Correct answer: B
Rationale: The priority nursing action in this scenario is to perform an ECG. An ECG is crucial in confirming myocardial infarction promptly and guiding immediate treatment decisions. Administering oxygen as prescribed is important but not the priority over confirming the diagnosis. Obtaining a detailed health history is relevant but does not take precedence over immediate diagnostic confirmation. While monitoring vital signs regularly is essential, performing an ECG is the priority action in this scenario to guide timely management.
2. Which membrane lines the abdominal cavity?
- A. Perineum
- B. Pericardium
- C. Pleura
- D. Peritoneum
Correct answer: D
Rationale: The correct answer is D, Peritoneum. The peritoneum is the membrane that lines the abdominal cavity, providing support to abdominal organs and serving as a conduit for their blood vessels. Choices A, B, and C are incorrect. The perineum refers to the area between the anus and the external genitalia, the pericardium is the membrane enclosing the heart, and the pleura is the membrane surrounding the lungs.
3. The nurse is monitoring a client with an IV infusion in the left antecubital fossa. The site is warm, red, and without swelling. What conclusion should the nurse draw from these findings?
- A. The IV fluids are infusing into the subcutaneous tissues
- B. The infusion pump is functioning properly
- C. The insertion date should be verified and the IV discontinued
- D. The site is inflamed and should be reported
Correct answer: B
Rationale: The correct answer is B. Warmth and redness at the IV site without swelling indicate a localized reaction, which is common and does not necessarily indicate infiltration of IV fluids into the subcutaneous tissues. The absence of swelling suggests that the IV is correctly placed. Therefore, the nurse should conclude that the infusion pump is functioning properly. Choice A is incorrect as warmth and redness alone do not indicate subcutaneous infiltration. Choice C is incorrect as discontinuing the IV solely based on warmth and redness without swelling is not necessary. Choice D is incorrect as the absence of swelling signifies a localized reaction rather than inflammation requiring immediate reporting.
4. Which nonfood item is the most common cause of respiratory arrest in young children?
- A. Broken rattles
- B. Buttons
- C. Pacifiers
- D. Latex balloons
Correct answer: D
Rationale: The correct answer is D, Latex balloons. Latex balloons can pose a significant choking hazard to young children if inhaled, potentially leading to respiratory arrest. Broken rattles, buttons, and pacifiers are not typically known to cause respiratory arrest in young children. While these items can present choking hazards as well, the most common cause of respiratory arrest among young children is due to inhaling latex balloons.
5. When reconstituted, how many milligrams are in each milliliter of solution?
- A. 300 mg/mL
- B. 350 mg/mL
- C. 450 mg/mL
- D. 400 mg/mL
Correct answer: D
Rationale: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.
