A nurse is caring for a patient with a history of asthma. The nurse should educate the patient to avoid which of the following triggers?

Correct Answer: B

Rationale: The correct answer is B: Cold, dry air. Cold, dry air is a common trigger for asthma exacerbations, as it can irritate the airways and lead to bronchoconstriction. This trigger can worsen asthma symptoms and increase the risk of an asthma attack. Educating the patient to avoid cold, dry air can help prevent asthma flare-ups. Explanation for why the other choices are incorrect: A: Exercise-induced asthma is triggered by physical activity but can be managed with proper warm-up and medication. It is not typically something to avoid altogether. C: Caffeine is a mild bronchodilator and can actually help alleviate asthma symptoms in some cases. D: Environmental allergens can trigger asthma in some individuals, but they vary from person to person, so avoidance strategies would depend on specific allergens identified through testing.

Correct Answer: D

Rationale: The correct answer is D: Clubbing of the nails. Clubbing is a physical finding associated with chronic respiratory conditions like emphysema and bronchitis. It is characterized by the softening of the nail bed and the loss of the normal angle between the nail and the nail bed. This occurs due to chronic hypoxia and can be a sign of advanced lung disease. Anasarca (choice A) is generalized edema, not specific to respiratory conditions. Scleroderma (choice B) is a connective tissue disorder affecting the skin and other organs, not directly related to respiratory conditions. Pedal erythema (choice C) refers to redness of the feet and is not a typical finding in emphysema or bronchitis.

Correct Answer: B

Rationale: The correct answer is B: Bleeding or perforation. After a colonoscopy, the patient is at risk for bleeding or perforation which are serious complications requiring immediate attention. Monitoring for signs such as abdominal pain, rectal bleeding, or signs of peritonitis is crucial. Choice A is not a priority unless the patient shows signs of shock. Choice C is a common post-procedure issue but not a priority complication. Choice D, pain at the insertion site, is expected and can be managed with analgesics.

Correct Answer: D

Rationale: The correct answer is D because it respects the girl's privacy and allows her to speak freely without parental influence. By asking the parents to step out, the nurse creates a safe space for the girl to discuss any sensitive issues. Choice A may inhibit the girl's honest communication. Choice B risks the parents dominating the conversation. Choice C may make the girl uncomfortable discussing personal matters in front of her parents.

Correct Answer: C

Rationale: The correct answer is C: Deep vein thrombosis (DVT). After knee replacement surgery, the patient is at a higher risk for developing DVT due to immobility and altered blood flow. Monitoring for signs such as calf pain, swelling, and redness is crucial to prevent complications like pulmonary embolism. Pulmonary embolism (Choice A) is a potential complication of untreated DVT. Gastrointestinal bleeding (Choice B) is not directly related to knee replacement surgery. Hypoglycemia (Choice D) is not a common complication post-knee replacement. Monitoring for DVT is essential in preventing life-threatening complications for the patient.

Correct Answer: A

Rationale: The correct answer is A because applying theory in real situations allows nurses to analyze, evaluate, and problem-solve effectively. This promotes critical thinking by integrating knowledge into practice. Working with physicians (B) and following orders (C) do not directly enhance critical thinking as they focus more on collaboration and task completion. Developing nursing diagnoses (D) is important but does not specifically target critical thinking skills like applying theory does.

Correct Answer: C

Rationale: The correct answer is C. After being in critical care for 10 days, it is expected that the patient may be disoriented to time but still be oriented to place and person. This is a common occurrence due to the stressful and disorienting environment of the critical care unit. The patient's cognition may be temporarily affected, leading to difficulty in remembering the date accurately. The patient's ability to recognize their surroundings and identify themselves and others should still be intact. Choices A, B, and D are incorrect because disruption in thought content, expressing relief, and clouding of consciousness are not typical cognitive function issues expected in this scenario.

Correct Answer: D

Rationale: The correct answer is D because obtaining information on the limitations related to the girl's involvement in sports activities is crucial for assessing her overall physical health and well-being. This information helps in understanding any potential risks or issues that may arise from her participation in sports. Choices A, B, and C are incorrect as they are not relevant to a review of systems for a healthy 7-year-old girl. Glaucoma examination, breast self-examination frequency, and electrocardiogram date are not typically part of a routine review of systems for a child of her age and health status.

Correct Answer: D

Rationale: The correct answer is D because it involves a specific and observable task that assesses attention span. By asking the patient to perform a physical action that requires focus and coordination, the nurse can directly evaluate the patient's ability to follow instructions and maintain attention. This task also helps to assess motor skills and coordination, which can be affected in certain conditions associated with anxiety and restlessness. Choices A, B, and C are incorrect because they do not directly assess attention span. Choice A focuses on emotions and behavior rather than attention. Choice B assesses memory recall rather than attention span. Choice C tests comprehension and interpretation skills related to a phrase, but it does not evaluate attention span directly.
