Mr. Santos a 59-year old businessman was diagnosed with angina pectoris. The nurse understands that the cause of angina pectoris is:
- A. decrease in the alveolar surface for gas exchange
- B. inadequate supply of oxygen to the myocardium
- C. inadequate blood pressure in the pulmonary circulation
- D. increase in the alveolar surface for gas exchange
Correct Answer: B
Rationale: The correct answer is B: inadequate supply of oxygen to the myocardium. Angina pectoris is chest pain or discomfort caused by reduced blood flow to the heart muscle. This lack of oxygenated blood supply to the myocardium leads to ischemia, resulting in the characteristic chest pain. Choice A is incorrect as it refers to a decrease in alveolar surface area for gas exchange, which is related to conditions like emphysema, not angina. Choice C is incorrect as it pertains to pulmonary circulation, not coronary circulation. Choice D is incorrect as an increase in alveolar surface area would not be a cause of angina pectoris.

- A. “Client will lose 2lb per week on a calorie-restricted diet.”
- B. “Client will exhibit no signs or symptoms of aspiration.”
- C. “Client will exhibit bowel and bladder continence.”
- D. “Client will exhibit alertness and orientation to person, place, and time.” DISTURBANCES IN IMMUNOLOGIC FUNCTIONING
Correct Answer: E
Rationale: I'm sorry, but it seems like the correct answer (E) is missing from the question. Could you please provide the correct answer so that I can provide you with a detailed explanation of why it is correct and summarize why the other choices are incorrect?
A patient returns from surgery ff. a TURP with a three-way Foley catheter and continuous bladder irrigation. Postoperative orders include Meperidine (Demerol) 75 mg IM q3h as needed for pain, belladonna and opium (B&O) suppository q4h as needed, and strict I&O. the patient complains of painful bladder spasms, and the nurse observes blood-tinged urine on the sheets. Which action should the nurse take?
- A. Give Demerol
- B. Give B&O suppository
- C. Warm the irrigation solution to body temperature
- D. Notify the physician stat
Correct Answer: D
Rationale: The correct action for the nurse to take is to notify the physician stat (choice D). Firstly, the patient presents with painful bladder spasms and blood-tinged urine, indicating a potential complication post-TURP. This warrants immediate medical attention to assess for possible bladder injury or hemorrhage. Giving Demerol (choice A) or B&O suppository (choice B) may provide symptomatic relief but does not address the underlying issue. Warming the irrigation solution (choice C) is not a priority in this situation and does not address the potential serious complications. Notifying the physician immediately allows for prompt evaluation and appropriate intervention to address the patient's condition effectively.
At a public health fair, a nurse discusses the dangers of sun exposure. Prolonged sun exposure has been blamed for which form of cancer?
- A. Malignant melanoma
- B. Basal cell epithelioma
- C. Squamous cell carcinoma
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D: All of the above. Malignant melanoma, basal cell epithelioma, and squamous cell carcinoma are all forms of skin cancer associated with prolonged sun exposure. Melanoma is the deadliest form, originating in melanocytes; basal cell and squamous cell carcinomas are more common but less aggressive. All three types can develop due to cumulative UV radiation exposure. Therefore, all options are correct in this context.
A client with Addison’s disease comes to the clinic for a follow-up visit. When assessing this client, the nurse should stay alert for signs and symptoms of:
- A. calcium and phosphorus abnormalities
- B. sodium and chloride abnormalities
- C. chloride and magnesium
- D. sodium and potassium abnormalities abnormalities.
Correct Answer: D
Rationale: The correct answer is D. In Addison's disease, the adrenal glands do not produce enough cortisol and aldosterone. This leads to sodium and potassium imbalances. Low aldosterone causes sodium loss and potassium retention, resulting in sodium and potassium abnormalities. The other choices, A, B, and C, do not directly relate to Addison's disease. Calcium and phosphorus abnormalities are not typically associated with Addison's disease. Sodium and chloride, and chloride and magnesium imbalances are not primary concerns in Addison's disease. Therefore, staying alert for signs and symptoms of sodium and potassium abnormalities is crucial in managing and monitoring a client with Addison's disease.
With pulmonary edema, there is usually an alteration in:
- A. Afterload
- B. Preload
- C. Contractility
- D. All of the above
Correct Answer: D
Rationale: Pulmonary edema causes an increase in pressure in the pulmonary circulation, leading to an alteration in afterload due to increased resistance. It also causes fluid accumulation in the pulmonary vessels, affecting preload. Additionally, the heart may compensate by increasing contractility. Therefore, all of the above choices are altered in pulmonary edema. The incorrect choices are A, B, and C individually as they only represent one aspect of the alterations seen in pulmonary edema, while the correct answer D encompasses all three factors affected in this condition.
