To appropriately monitor therapy and client progress, the nurse should be aware that increased myocardial work and O2 demand will occur with which of the following?
- A. Positive inotropic therapy
- B. Negative chronotropic therapy
- C. Increase in balance of myocardial O2 supply and demand
- D. Afterload reduction therapy
Correct Answer: A
Rationale: Inotropic therapy will increase contractility, which will increase myocardial O2 demand. Decreased heart rate to the point of bradycardia will increase coronary artery filling time. This should be used cautiously because tachycardia may be a compensatory mechanism to increase cardiac output. The goal in the care of the MI client with angina is to maintain a balance between myocardial O2 supply and demand. Decrease in systemic vascular resistance by drug therapy, such as IV nitroglycerin or nitroprusside, or intra-aortic balloon pump therapy, would decrease myocardial work and O2 demand.

A client with a history of a bone marrow transplant is receiving immunosuppressive therapy. The nurse should monitor the client for:
- A. Infection
- B. Hypotension
- C. Hyperglycemia
- D. Hair loss
Correct Answer: A
Rationale: Immunosuppressive therapy post-bone marrow transplant increases infection risk due to suppressed immunity. Hypotension, hyperglycemia, and hair loss are less immediate concerns.
The physician has ordered an intravenous infusion of Pitocin for the induction of labor. When assessing the client’s response to the Pitocin, the nurse should give priority to:
- A. Monitoring the blood pressure
- B. Checking the fetal heart rate
- C. Timing the frequency of contractions
- D. Assessing the urinary output
Correct Answer: B
Rationale: Pitocin can cause uterine hyperstimulation, risking fetal distress. Checking the fetal heart rate is the priority to ensure fetal well-being. Blood pressure, contractions, and urinary output are monitored but are secondary to fetal status.
The serial sevens test is often used to determine delirium and dementia. This test aids in assessing which of the following?
- A. Abstract thinking
- B. Ability to focus and concentrate thoughts
- C. Judgment
- D. Memory
Correct Answer: B
Rationale: This answer is incorrect. The test measures the abilities to concentrate and calculate. The use of proverbs is the most common way to test abstraction. This answer is correct. The serial sevens test is a common test of calculation ability. It is difficult for the demented or delirious client to perform. This answer is incorrect. The test for judgment should predict whether the individual will behave in a socially accepted manner. This answer is incorrect. In testing memory, the nurse would attempt to get the client either to recall recent events or to think about past events.
The nurse is caring for a client with a T4 spinal cord injury. The client complains of a pounding headache. The nurse should:
- A. Check the client’s blood pressure
- B. Administer the client’s ordered pain medication
- C. Place the client in a sitting position
- D. Notify the physician immediately
Correct Answer: A
Rationale: A pounding headache in a T4 spinal cord injury suggests autonomic dysreflexia, often triggered by bladder or bowel issues, causing severe hypertension. Checking blood pressure is the priority to confirm.
Which diet would the nurse expect to see ordered for a patient with nephrotic syndrome?
- A. Low carbohydrate potassium
- B. Moderate protein
- C. Low calcium
- D. Increased potassium
Correct Answer: B
Rationale: Nephrotic syndrome causes proteinuria, leading to hypoalbuminemia. A moderate protein diet (0.8–1 g/kg/day) helps replace lost protein without overloading the kidneys. Low carbohydrate, low calcium, or increased potassium diets are not specific to nephrotic syndrome.
