Which of the following ECG changes would be seen as a positive myocardial stress test response?

  1. Hyperacute T wave
  2. Prolongation of the PR interval
  3. ST-segment depression
  4. Pathological Q wave

Answer(s): C

Explanation:

(A) Hyperacute T waves occur with hyperkalemia. (B) Prolongation of the P R interval occurs with first-degree AV block. (C) Horizontal ST-segment depression of>1 mm during exercise isdefinitely a positive criterion on the exercise ECG test. (D) Patho-logical Q waves occur with MI.



The primary reason for sending a burn client home with a pressure garment, such as a Jobst garment, is that the garment:

  1. Decreases hypertrophic scar formation
  2. Assists with ambulation
  3. Covers burn scars and decreases the psychological impact during recovery
  4. Increases venous return and cardiac output by normalizing fluid status

Answer(s): A

Explanation:

(A) Tubular support, such as that received with a Jobst garment, applies tension of 10­20 mm Hg. This amount of uniform pressure is necessary to prevent or reduce hypertrophic scarring. Clients typically wear a pressure garment for 6­12 months during the recovery phase of their care. (B) Pressure garments have no ambulatory assistive properties. (C) Pressure garments can worsen the psychological impact of burn injury, especially if worn on the face. (D) Pressure garments do not normalize fluid status.



A 25-year-old client believes she may be pregnant with her first child. She schedules an obstetric examination with the nurse practitioner to determine the status of her possible pregnancy. Her last menstrual period began May 20, and her estimated date of confinement using Nägele's rule is:

  1. March 27
  2. February 1
  3. February 27
  4. January 3

Answer(s): C

Explanation:

(A)March 27 is a miscalculation. (B) February 1 is a miscalculation. (C) February 27 is the correct answer. To calculate the estimated date of confinement using Nagele's rule, subtract 3 months from the date that the last menstrual cycle began and then add 7 days to the result. (D) January 3 is a miscalculation.



A male client receives 10 U of regular human insulin SC at 9:00 AM. The nurse would expect peak action from this injection to occur at:

  1. 9:30 AM
  2. 10:30 AM
  3. 12 noon
  4. 4:00 PM

Answer(s): C

Explanation:

(A) This is too early for peak action to occur. (B) This is too early for peak action to occur. (C) Regular insulin peak action occurs 2­4 hours after administration. (D) This is too late for peak action to occur.



Which classification of drugs is contraindicated for the client with hypertrophic cardiomyopathy?

  1. Positive inotropes
  2. Vasodilators
  3. Diuretics
  4. Antidysrhythmics

Answer(s): A

Explanation:

(A) Positive inotropic agents should not be administered owing to their action of increasing myocardial contractility. Increased ventricular contractility would increase outflow tract obstruction in the client with hypertrophic cardiomyopathy. (B) Vasodilators are not typically prescribed but are not contraindicated. (C) Diuretics are used with caution to avoid causing hypovolemia. (D) Antidysrhythmics are typically needed to treat both atrial and ventricular dysrhythmias.
