Wilma knew that the maximum time when suctioning James is

Correct Answer: C

Rationale: The correct answer is C (30 seconds) because the maximum recommended time for suctioning a patient is typically around 10-15 seconds for each pass. Prolonged suctioning can lead to tissue damage, hypoxia, and increased risk of infection. In this case, given the patient's symptoms and medical history (vomiting, weight loss, dehydration, hypotension), it is crucial to limit suction time to prevent further complications. Choices A, B, and D are incorrect as they exceed the safe duration for suctioning and increase the risk of harm to the patient. Choice D, in particular, is significantly longer than the recommended time and could pose serious risks to the patient's health in this situation.

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: D

Rationale: The correct answer is D: Reduce airway inflammation. Corticosteroids like methylprednisolone are used in emphysema to reduce inflammation in the airways, which can help improve lung function and symptoms. Corticosteroids work by suppressing the immune response that leads to inflammation in the airways. This can help decrease swelling, mucus production, and constriction of the airways, all of which contribute to the symptoms of emphysema. Dry secretions (choice A) and improving oxygen-carrying capacity (choice B) are not the primary purposes of corticosteroid treatment in emphysema. Treating infection that causes a low level of hemoglobin (choice C) is not relevant to corticosteroid treatment for emphysema.

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.
