The nurse, who is serving as a preceptor for a graduate nurse, frequently asks questions to assess the graduate nurse's level of knowledge. The nurses are discussing the effects of H1 versus H2 receptors.

The graduate nurse correctly states that the major response to the activation of H2 re-ceptors is a. nausea and vomiting.
b. vasodilation of cutaneous vessels.
c. functioning as an antagonist for H1.
d. secretion of gastric acid.

Question 2

A patient who has been taking propranolol (Inderal) for 18 months reports, I stopped taking the medication yesterday, because my blood pressure has been normal for the past 3 months.

The most appropriate response by the nurse would be which of the following statements? a. Keep an accurate record of your blood pressure and come to the clinic next week.
b. Have you had any chest pain or palpitations?
c. You should come to the emergency department immediately. The drug should be tapered over 2 weeks to prevent rebound hypertension.
d. Continue taking the medication until another can be started to prevent with-drawal symptoms.

Answer to Question 1

D
The major response to activation of H2 receptors is secretion of gastric acid.
Nausea and vomiting are not responses to H2 activation.
Vasodilation of cutaneous vessels is not a response to H2 activation.
H2 does not act as an antagonist for H1.

Answer to Question 2

C
The patient should come to the emergency department immediately, because rebound hyperten-sion can occur when propranolol is stopped without weaning or tapering.
The patient should not wait until next week to be seen, because rebound hypertension can be-come life-threatening. The patient should be instructed to come to the emergency department immediately.
Although asking about chest pain and palpitations may be important, sudden withdrawal from propranolol can lead to rebound hypertension, and the patient should be seen immediately.
The patient states that he has already stopped taking the medication, and having him resume tak-ing it is not going to make up for the adverse effects that may occur from sudden withdrawal. The patient should be seen immediately.
