When evaluating the effectiveness of nursing interventions for sinusitis discomfort, which of the following does the nurse assess?

Correct Answer: C

Rationale: The correct answer is C: Amount and color of sinus drainage. Assessing the amount and color of sinus drainage is crucial in evaluating the effectiveness of nursing interventions for sinusitis discomfort as it indicates the presence of infection or inflammation. Changes in color or amount can signify improvement or worsening of the condition. WBC count (A) may indicate infection but doesn't directly reflect sinusitis discomfort. Capillary refill (B) assesses circulation, not sinusitis. Comfort level (D) is subjective and can vary among individuals, making it less reliable for assessing the effectiveness of interventions.

Correct Answer: C

Rationale: The correct answer is C: Paroxysms or shortness of breath. Asthma is characterized by episodes of wheezing, coughing, chest tightness, and shortness of breath, known as paroxysms. This symptom is caused by inflammation and constriction of the airways in response to triggers such as allergens or irritants. A: Production of abnormally thick, sticky mucus in lungs is more indicative of conditions like cystic fibrosis, not asthma. B: Faulty transport of sodium in lung cells is associated with conditions like cystic fibrosis, not asthma. D: Altered electrolyte balance in the sweat glands is a symptom of cystic fibrosis, not asthma. In summary, paroxysms or shortness of breath is a key sign of asthma due to airway inflammation and constriction, distinguishing it from the other choices that are more indicative of cystic fibrosis.

Correct Answer: D

Rationale: The correct answer is D: Turn off the antibiotic. This should be the nurse's first action because in an anaphylactic reaction, stopping the administration of the causative agent is crucial to prevent further harm. Continuing the antibiotic (Choice B) can worsen the reaction. Calling the doctor (Choice A) may cause a delay in the immediate intervention needed. Calling for help (Choice C) is important but turning off the antibiotic takes precedence to stop the allergen.

Correct Answer: C

Rationale: The correct answer is C because antihistamines can suppress the immune response that the skin test is designed to detect, leading to false negative results. By inhibiting the body's allergic response, antihistamines can mask the presence of an allergy, giving the false impression that the individual is not allergic to a particular substance. This can lead to misdiagnosis and improper treatment. Choices A, B, and D are incorrect because antihistamines do not affect bleeding, aggravate allergic reactions, or cause wheezing in the context of a skin test.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Timing: Antiviral medications should be taken as prescribed to maintain consistent drug levels in the body. 2. Around meals: Taking medications with or without food can affect absorption, so timing around meals helps with consistency. 3. Compliance: Following the timing instructions increases medication effectiveness and reduces the risk of drug resistance. Other Choices: B) Avoiding harsh sunlight: Not directly related to medication administration; may be a precaution for other reasons. C) Having medications with fruit juice: This is not a standard instruction for antiviral medications; may not be suitable for all medications. D) Increasing dose for worsening symptoms: This is dangerous and should only be done under healthcare provider supervision; self-adjusting medication doses can be harmful.
