1. The healthcare provider has administered albuterol as an inhaled medication. The healthcare provider should monitor the client for which possible adverse reaction?
- A. Enuresis
- B. Lethargy
- C. Depression
- D. Tachycardia
Correct answer: D
Rationale: Albuterol is a bronchodilator in the adrenergic category. Its actions and adverse effects are similar to adrenaline or epinephrine. The healthcare provider should monitor the client for tachycardia, which is a common adverse effect of albuterol due to its stimulant effect on beta-2 receptors. Enuresis, or night bed-wetting, is not an adverse effect associated with albuterol. Additionally, the client should be monitored for anxiety as a potential adverse effect, not lethargy or depression, which are not typically associated with albuterol administration.
2. A client receiving enalapril reports a persistent dry cough. The nurse should explain that this side effect is related to which medication action?
- A. It reduces the production of angiotensin II.
- B. It increases the production of angiotensin II.
- C. It causes increased production of bradykinin.
- D. It increases the production of aldosterone.
Correct answer: C
Rationale: The correct answer is C. Enalapril, an ACE inhibitor, inhibits the conversion of angiotensin I to angiotensin II, leading to increased levels of bradykinin. The accumulation of bradykinin is responsible for the persistent dry cough associated with ACE inhibitors like enalapril. Choices A, B, and D are incorrect because enalapril does not directly affect the production of angiotensin II or aldosterone. Instead, it primarily impacts the renin-angiotensin-aldosterone system by inhibiting the conversion of angiotensin I to angiotensin II, leading to bradykinin accumulation.
3. A patient with irritable bowel syndrome starts a new prescription for dicyclomine, an anticholinergic medication. The client reports the onset of sensitivity to light and a dry mouth. How should the nurse respond?
- A. Determine if the medication is being taken correctly
- B. Provide instructions on managing these side effects
- C. Schedule an appointment for evaluation by the healthcare provider
- D. Advise stopping the medication until the unpleasant side effects wear off
Correct answer: B
Rationale: The correct response is to provide instructions on managing these side effects. Sensitivity to light and dry mouth are common side effects of anticholinergic medications like dicyclomine. It is essential for the nurse to educate the patient on strategies to cope with these side effects, such as staying hydrated to address dry mouth and wearing sunglasses to reduce sensitivity to light. Option A is not the priority as the side effects are expected with this medication and do not necessarily indicate incorrect use. Option C is not immediately necessary as the side effects are common and can be managed without a healthcare provider evaluation. Option D is not recommended unless advised by the healthcare provider as abruptly stopping the medication can lead to worsening symptoms or withdrawal effects.
4. A client with a diagnosis of generalized anxiety disorder is prescribed buspirone. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct potential side effect of buspirone is drowsiness. It is important for clients to be informed about this side effect, as it can affect their ability to perform tasks that require full alertness, such as driving. Clients should be advised to avoid activities that require mental alertness until they know how the medication affects them. Dry mouth is a common side effect of some other medications used for anxiety, such as benzodiazepines. Nausea and headache are not typically associated with buspirone use.
5. A client with a diagnosis of schizophrenia is prescribed olanzapine. The nurse should monitor for which potential side effect?
- A. Weight gain
- B. Insomnia
- C. Dry mouth
- D. Headache
Correct answer: A
Rationale: When a client with schizophrenia is prescribed olanzapine, the nurse should monitor for weight gain as a potential side effect. Olanzapine is known to cause metabolic changes that can lead to weight gain, making it crucial for the nurse to closely monitor the client's weight during treatment. This side effect is significant as it can impact the client's overall health and well-being, so early detection and intervention are essential to manage it effectively.
