Nokea
A nurse is monitoring the vital signs of a client who has received epinephrine. The nurse would report which of the following assessment findings?
- A. Systolic blood pressure below 100 mm Hg
- B. Temperature reading of 97.6°F
- C. Pulse rate of 60 beats/min
- D. A diastolic blood pressure of 75 mm Hg
Correct Answer: A
Rationale: A systolic blood pressure below 100 mm Hg indicates that epinephrine, which should raise blood pressure, is not effective and requires immediate reporting.

A client has been administered dobutamine. The client is also receiving a beta-adrenergic blocking drug. The nurse would monitor the client for the development of which of the following resulting from the use of these two drugs?
- A. Bradycardia
- B. Hypertension
- C. Depression
- D. Dehydration
Correct Answer: B
Rationale: The combination of dobutamine and beta-blockers can lead to hypertension due to unopposed alpha-adrenergic effects when beta receptors are blocked.
A nurse is caring for a client who has recently suffered an acute myocardial infarction. The nurse would closely monitor this client for which of the following that would suggest that the client is developing shock?
- A. Increased blood pressure
- B. Decreased urinary output
- C. Hypoxia
- D. Tachypnea
- E. Bradycardia
Correct Answer: B,C,D
Rationale: Signs of shock include decreased urinary output, hypoxia, and tachypnea due to inadequate tissue perfusion. Increased blood pressure and bradycardia are not typical signs of shock.
Ma huang is an herbal product that has been used to relieve cold symptoms and for weight loss. The nurse would instruct a client receiving which of the following to avoid products containing ma huang?
- A. Digoxin (Lanoxin)
- B. Phenelzine (Nardil)
- C. Guanethidine (Ismelin)
- D. Oxytocin (Pitocin)
- E. Halothane (Avestan)
Correct Answer: A,B,C,D,E

When describing the adrenergic nervous system, which of the following would the instructor describe as two types of receptors that are found in this system?
- A. Alpha receptors
- B. Beta receptors
- C. Delta receptors
- D. Gamma receptors
- E. Omega receptors
Correct Answer: A,B
Rationale: The adrenergic nervous system involves alpha and beta receptors, which mediate the effects of catecholamines like norepinephrine and epinephrine.
A nurse is reviewing the effects of adrenergic drugs on the body. The nurse demonstrates understanding of this group of drugs by identifying that which of the following would occur if the drug stimulates beta-1 receptors?
- A. Vasoconstriction of peripheral blood vessels
- B. Decreased gastrointestinal tract secretions
- C. Increased force of myocardial contractions
- D. Bronchodilation
Correct Answer: C
Rationale: Beta-1 receptor stimulation increases heart rate and myocardial contractility, enhancing cardiac output.
