Question 1 of 5
A client with a history of chronic obstructive pulmonary disease (CORD) and type 2 diabetes has been treated for pneumonia for the past week. The client has been receiving intravenous corticosteroids as part of his therapy. At this time, the pneumonia has resolved, but when monitoring the blood glucose levels, the nurse notices that the level is still elevated. What is the best explanation for this elevation?
Correct Answer: B
Rationale: Corticosteroids have a counter-regulatory effect, increasing glucose levels.
Question 2 of 5
The nurse is evaluating the laboratory results of a client who has received chemotherapy. The loss of which blood cell leads to lack of energy, fatigue, intolerance of activity and hypoxemia?
Correct Answer: C
Rationale: Red blood cells carry oxygen, and their loss causes fatigue and hypoxemia.
Question 3 of 5
A client who has received chemotherapy has a critically low platelet count. The nurse expects which drug or drug class to be used to stimulate platelet cell production?
Correct Answer: B
Rationale: Oprelvekin promotes platelet production.
Question 4 of 5
A client arrives in the emergency department with severe chest pain. The client reports that the pain has been occurring off and on for a week now. Which assessment finding would indicate the need for cautious use of nitrates and nitrites?
Correct Answer: A
Rationale: Nitrates and nitrites are vasodilators and could worsen existing hypotension.
Question 5 of 5
An adrenergic agonist is ordered for a client in cardiogenic shock. The nurse will note that this drug has had its primary intended effect if which expected outcome occurs?
Correct Answer: A
Rationale: An agonist means it binds to mimic the action of the endogenous neurotransmitter. Adrenergic receptors act to stimulate the sympathetic nervous system leading to the fight/flight response. Increase in heart rate leads to increased cardiac output.
