C: Hypotension doesn't pose a significant risk with decongestants, as these drugs typically raise blood pressure rather than lower it, making caution less necessary in this case.
D: Hypothyroidism does not directly impact the safe administration of decongestants, as these medications do not interfere with thyroid function or hormone levels.
E: Arthritis is not a condition that necessitates caution with decongestants, as these drugs do not typically worsen joint inflammation or pain associated with arthritis.
Question 24
Multiple Choice
After teaching a group of nursing students about antihistamines, the instructor determines that the teaching was successful when the students identify which of the following as less sedating? Select all that apply.
Correct!
Incorrect
The correct answer is: A,B,C
Rationale
Loratadine (Claritin), Fexofenadine (Allegra), and Cetirizine (Zyrtec) are recognized as less sedating antihistamines due to their formulations that minimize crossing the blood-brain barrier, allowing for effective allergy relief with reduced drowsiness.
D: Brompheniramine (Lodrane) possesses sedative properties due to its first-generation antihistamine classification, which commonly causes drowsiness in users, making it unsuitable for those seeking non-sedating options.
E: Clemastine (Tavist) is also a first-generation antihistamine, leading to significant sedation and side effects, rendering it less favorable for individuals needing to maintain alertness during daily activities.

Question 25
Multiple Choice
A client taking metoprolol (Lopressor) 50 mg one tablet twice daily begins taking over-the-counter pseudoephedrine. The nurse would assess for which of the following? Select all that apply.
Correct!
Incorrect
The correct answer is: B,E
Rationale
B: Hypertensive episode and E: Bradycardic episode are critical assessments due to metoprolol’s effects on heart rate and blood pressure. Pseudoephedrine can counteract these effects, leading to elevated blood pressure and potential decreased heart rate, necessitating careful monitoring.
A: Hyperglycemic episode does not relate to the combination of metoprolol and pseudoephedrine, as neither medication significantly impacts blood glucose levels in this context.
C: Rebound congestion typically occurs with prolonged use of decongestants, not from the combination of metoprolol and pseudoephedrine, which does not directly cause this effect.
D: Hypoglycemic episode is not a concern with metoprolol and pseudoephedrine, as these medications do not induce low blood sugar levels in patients when taken as prescribed.

Question 26
Multiple Choice
A client is suffering from rebound congestion. Which of the following would the nurse expect to do to help the client experience relief from rebound congestion? Select all that apply.
Correct!
Incorrect
The correct answer is: A,D,E
Rationale
Switching from a topical decongestant to an oral product, gradually discontinuing the decongestant, and suggesting saline irrigation can effectively alleviate rebound congestion by reducing dependence on topical agents and promoting nasal moisture.
A: Suggest the client switch from a topical decongestant to an oral product. Transitioning to an oral decongestant helps mitigate reliance on topical options, thereby alleviating rebound congestion effectively.
B: Recommend the client switch from an oral decongestant to a topical product. Moving to a topical option can exacerbate rebound congestion, as it may create further dependence on nasal sprays.
C: Tell the client to abruptly discontinue the decongestant product. Sudden cessation can lead to intensified symptoms of rebound congestion, worsening the client's condition instead of providing relief.
D: Advise the client to gradually discontinue the decongestant product. Gradual tapering minimizes withdrawal symptoms and allows the nasal passages to adjust without overwhelming irritation or congestion.
E: Suggest a saline irrigation of the nasal passages in place of the decongestant. Saline irrigation provides moisture and clears nasal passages without the rebound effects associated with decongestants.

Question 27
Multiple Choice
A client complains of increased sedation after the initiation of chlorpheniramine to treat her allergies. Which of the following would the nurse suggest to the client to treat her allergy symptoms that would result in less sedation? Select all that apply.
Correct!
Incorrect
The correct answer is: C,D
Rationale
Ioratadine (Claritin) and Cetirizine (Zyrtec) are both second-generation antihistamines that are less likely to cause sedation compared to chlorpheniramine. These medications selectively block histamine receptors with minimal central nervous system penetration, making them suitable alternatives for allergy symptom relief.
A: Diphenhydramine (Benadryl) Causes significant sedation as it readily crosses the blood-brain barrier, leading to drowsiness, which is not desirable for clients needing allergy relief without increased sedation.
B: Clomastine (Tavist) Similar to diphenhydramine, clomastine is a first-generation antihistamine that frequently induces sedation due to its central nervous system activity, making it unsuitable for this client's needs.
E: Phenylephrine (Neo-Synephrine) As a decongestant, phenylephrine does not address allergy symptoms related to histamine release, making it ineffective for treating the client’s allergy-related symptoms specifically.

Question 28
Regular
A client with vasomotor rhinitis has been prescribed an antihistamine. The client is eager to know whether the prescribed antihistamine may cause excessive sedation. Which antihistamine would the nurse identify as having very little sedative effect?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Azelastine is an antihistamine that is known for its minimal sedative effects, making it suitable for patients concerned about drowsiness while managing symptoms of vasomotor rhinitis effectively.
A: Brompheniramine typically causes sedation due to its first-generation antihistamine properties, which often lead to drowsiness and should be avoided by those needing to stay alert.
B: Clemastine has sedative qualities associated with first-generation antihistamines, which can significantly impair cognitive and motor functions, making it less desirable for patients concerned about sedation.
C: Chlorpheniramine tends to induce sedation as well, being another first-generation option that can cause unwanted drowsiness, thus not ideal for individuals prioritizing alertness.

Question 29
Regular
A client has been prescribed a decongestant drug for congestion associated with rhinitis. When teaching the client about this drug, which of the following would the nurse include as a possible adverse reaction?
Correct!
Incorrect
The correct answer is: B
Rationale
Blurred vision. Decongestants can affect the eyes by causing pupil dilation and altering accommodation, leading to temporary blurred vision as a side effect. Patients should be made aware of this possibility during education.
A: Decreased pulse rate. Decongestants typically stimulate the sympathetic nervous system, which generally results in an increased, not decreased, heart rate. This action counteracts the expected effects of these medications.
C: Drowsiness. Most decongestants are stimulants that can cause increased alertness and energy, rather than drowsiness, which is more commonly associated with antihistamines or other sedating medications.
D: Dryness of throat. While dryness can occur, it is more typical with antihistamines. Decongestants primarily work by constricting blood vessels in the nasal passages, not directly causing dryness in the throat.

Question 30
Regular
A client with allergic rhinitis is prescribed an antihistamine. The nurse instructs the client to suck on sugarless hard candy to address which of the following?
Correct!
Incorrect
The correct answer is: D
Rationale
Sucking on sugarless hard candy helps alleviate dryness of the oral mucosa and the throat caused by antihistamine medications, which can lead to decreased saliva production and increased discomfort.
A: Drowsiness and sedation Antihistamines may cause drowsiness; however, sugarless hard candy does not mitigate this side effect or influence the sedation levels experienced by the client.
B: Thickening of the bronchial secretions Antihistamines primarily reduce mucus production but do not directly address bronchial secretion thickness, so candy won't impact this aspect of the client's condition.
C: Altered sensation of taste While antihistamines can affect taste sensations, sucking on candy does not restore or improve taste perception, making this option irrelevant to the client's needs.
Correct Answer: D

Question 31
Regular
A 21-year-old client complains of a mild stinging sensation on using a nasal spray decongestant. Which response by the nurse would be most appropriate?
Correct!
Incorrect
The correct answer is: C
Rationale
This sensation is common and usually disappears with continued use.
Continued use of nasal spray decongestants often leads to adaptation, and mild stinging can be a temporary side effect that resolves as the body adjusts to the medication.
A: You need to stop the medication immediately. Stopping the medication may be unnecessary, as mild stinging is not uncommon and may resolve without discontinuation.
B: The dose is probably too strong and needs to be reduced. A dose reduction is not warranted since mild stinging can occur at standard dosages and often diminishes over time.
D: We better contact your primary health care provider right away. Immediate contact with a healthcare provider is excessive for a typical side effect like mild stinging, which usually resolves itself.

Question 32
Regular
A client has been prescribed a nasal decongestant for nasal stuffiness due to a common cold. The client is also taking an antidepressant that is a monoamine oxidase inhibitor. The nurse would warn the client about which of the following.
Correct!
Incorrect
The correct answer is: B
Rationale
Severe headache.
Monoamine oxidase inhibitors can interact with nasal decongestants, leading to increased blood pressure and the risk of hypertensive crisis, which often presents as severe headache. This combination requires careful monitoring to prevent complications.
A: Hypotension. Nasal decongestants primarily cause vasoconstriction, potentially leading to increased blood pressure rather than hypotension, making this option less relevant in the context of the given medications.
C: Sedation. Nasal decongestants typically do not induce sedation; their main action is to relieve congestion, and they are generally not associated with central nervous system depressant effects.
D: Bradycardia. The use of nasal decongestants is more likely to cause increased heart rate due to vasoconstriction effects, rather than leading to a decrease in heart rate or bradycardia.
