Question 1 of 5
When a client is receiving vasoactive therapy IV, such as dopamine (Intropin), and extravasation occurs, the nurse should be prepared to administer which of the following medications directly into the site?
Correct Answer: A
Rationale: Phentolamine is given to counteract the-adrenergic effects that cause ischemia and necrosis of local tissue. Epinephrine is an endogenous catecholamine that produces vasoconstriction and increases heart rate and contractility. Phenylephrine causes constriction of arterioles of skin, mucous membranes, and viscera, which in turn can cause ischemia and necrosis. Sodium bicarbonate is an alkalinizing agent that is incompatible with dopamine.
Question 2 of 5
A 52-year-old client is scheduled for a small-bowel resection in the morning. In conjunction with other preoperative preparation, the nurse is teaching her diaphragmatic breathing exercises. She will teach the client to:
Correct Answer: A
Rationale: This is the correct method of teaching diaphragmatic breathing, which allows full lung expansion to increase oxygenation, prevent atelectasis, and move secretions up and out of the lungs to decrease risk of pneumonia. Quick, short breaths do not allow for full lung expansion and movement of secretions up and out of the lungs. Quick, short breaths may lead to O2 depletion, hyperventilation, and hypoxia. Expelling breaths through the nose does not allow for full lung expansion and the use of diaphragmatic muscles to assist in moving secretions up and out of the lungs. Inhaling and exhaling at a rate of 20-24 times/min does not allow time for full lung expansion to increase oxygenation. This would most likely lead to O2 depletion and hypoxia.
Question 3 of 5
The nurse needs to be aware that the most common early complication of a myocardial infarction is:
Correct Answer: D
Rationale: Myocardial infarction causes tissue damage, which may interrupt electrical impulses. Myocardial irritability results from lack of oxygenated tissue.
Question 4 of 5
The nurse is caring for a client who is receiving terbutaline for preterm labor. Which side effect should the nurse monitor for?
Correct Answer: C
Rationale: Terbutaline a beta-agonist tocolytic commonly causes maternal tachycardia due to its stimulatory effects on the cardiovascular system. Maternal bradycardia fetal hypoglycemia and macrosomia are not associated side effects.
Question 5 of 5
A client with a history of chronic lymphocytic leukemia is admitted with complaints of fever. The nurse should give priority to:
Correct Answer: A
Rationale: Fever in chronic lymphocytic leukemia suggests possible infection, a serious complication due to immunosuppression, so monitoring for infection is the priority.
