D: A diastolic blood pressure of 75 mm Hg. This diastolic reading falls within the normal range and does not suggest any alarming changes following the administration of epinephrine, which usually affects systolic pressure more significantly.
Question 23
Regular
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?
Correct!
Incorrect
The correct answer is: B
Rationale
Dobutamine administration alongside a beta-adrenergic blocker can lead to hypertension. This combination enhances cardiac output, which may cause an increase in blood pressure, necessitating careful monitoring for potential hypertensive episodes.
A: Bradycardia The use of dobutamine typically increases heart rate, counteracting bradycardia; thus, the combination with a beta-blocker would not primarily lead to slower heart rates.
C: Depression Beta-adrenergic blockers can sometimes be associated with mood changes, but the combination with dobutamine does not directly relate to the development of depressive symptoms in this context.
D: Dehydration There is no direct link between dobutamine, beta-blockers, and dehydration; these medications primarily affect cardiovascular parameters rather than fluid balance in the body.

Question 24
Regular
A nurse is teaching a client how to use an auto-injector as treatment for an allergic reaction. Which statement by the client indicates the need for additional teaching?
Correct!
Incorrect
The correct answer is: B
Rationale
I should administer the dose and then call 9-1-1 if I'm alone.
This statement indicates a misunderstanding of the urgency following an auto-injector use. While calling 9-1-1 is essential, administering the dose should be followed by immediate action to seek help, not delayed if alone. Timely medical intervention is crucial in severe allergic reactions, making this statement a red flag for additional teaching.
A: I should not touch the orange or black tip on the small end. This statement demonstrates proper understanding of auto-injector safety, highlighting the need to avoid contact with critical components to prevent accidental activation.
C: I should inject the black tip into my outer thigh. This statement accurately describes the correct administration site for the auto-injector, ensuring that the medication is delivered effectively for an allergic reaction.
D: I need to massage the site after removing the device. This statement reflects a misunderstanding, as massaging the injection site can interfere with medication absorption and is not recommended after using an auto-injector.

Question 25
Multiple Choice
A client is prescribed norepinephrine IV. Which of the following would be appropriate for the nurse to do?
Correct!
Incorrect
The correct answer is: C,D,E
Rationale
Continuously monitor the client's blood pressure. Close observation of blood pressure is essential when administering norepinephrine, as it helps manage potential side effects and ensures the drug's effectiveness in critical situations.
A: Administer the drug via a gravity infusion. Norepinephrine requires precise dosing and control, making gravity infusion unsuitable for maintaining the necessary therapeutic levels during critical care.
B: Dilute the drug with sterile saline. Norepinephrine should not be diluted with saline, as this can alter its concentration and efficacy, potentially leading to ineffective treatment.
D: Check the IV insertion site for leakage. While important, this action does not directly address the critical need for monitoring blood pressure during norepinephrine administration, which is vital for patient safety.
E: Assess the client's urinary output hourly. Although important for overall patient assessment, it does not directly correlate with the immediate monitoring and management required for norepinephrine administration.

Question 26
Regular
While assessing a client, the nurse observes hives and flushing. The client reports itching and a tightness in the throat. The nurse would identify which of the following nursing diagnoses?
Correct!
Incorrect
The correct answer is: A
Rationale
Risk for Allergy Response. The symptoms of hives, flushing, itching, and throat tightness strongly indicate an allergic reaction, making this nursing diagnosis appropriate as it addresses potential allergic responses and requires monitoring.
B: Ineffective Tissue Perfusion. This option suggests a problem with blood flow, which does not correlate with the client’s reported allergic symptoms and their specific manifestations of an allergy.
C: Decreased Cardiac Output. This diagnosis implies a reduction in heart efficiency, which does not relate to the client's acute allergic signs and does not address the immediate concerns.
D: Risk for Injury. While the client may experience discomfort, this option does not directly address the underlying allergic response and fails to prioritize the urgency of the symptoms observed.

Question 27
Regular
After teaching a group of nursing students about adrenergic drugs and their effects, the instructor determines that the teaching was successful when the students identify which of the following as an effect of these drugs?
Correct!
Incorrect
The correct answer is: C
Rationale
Increased cardiac output. Adrenergic drugs stimulate the sympathetic nervous system, leading to enhanced heart rate and myocardial contractility, thereby significantly boosting cardiac output, a key effect sought in various medical situations.
A: Decreased myocardial contractility. Adrenergic drugs actually promote increased myocardial contractility rather than decreasing it, making this option inconsistent with their primary pharmacological effects.
B: Vasodilation. While some adrenergic receptors can mediate vasodilation, the primary effect of adrenergic drugs typically involves vasoconstriction to elevate blood pressure, contradicting this choice.
D: Improved airway clearance. Adrenergic drugs may aid in bronchodilation, but they do not directly enhance airway clearance, which is not their main therapeutic purpose.

Question 28
Regular
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?
Correct!
Incorrect
The correct answer is: C
Rationale
Increased force of myocardial contractions. Stimulation of beta-1 receptors primarily affects the heart, leading to enhanced myocardial contractility, which strengthens the heart's pumping ability and improves overall cardiac output.
A: Vasoconstriction of peripheral blood vessels. This effect is typically associated with alpha receptors, not beta-1 receptors, which focus on cardiac effects rather than peripheral vascular resistance.
B: Decreased gastrointestinal tract secretions. While adrenergic stimulation can reduce gastrointestinal activity, beta-1 receptors are specifically tied to cardiac function, not gastrointestinal secretions.
D: Bronchodilation. Bronchodilation is primarily mediated by beta-2 receptors, not beta-1. Beta-1 receptors are focused on increasing heart contractility rather than influencing respiratory pathways.
