1. You have a patient who has just had a diagnostic arthroscopy. You are instructing him about what to do when he gets home. Which of the following would you NOT instruct him to do?
- A. Resume normal activities within 12 hours so as to help reduce the swelling
- B. Elevate the extremity for 24 – 48 hours
- C. Apply ice to the area involved intermittently
- D. Report severe pain to the physician immediately
Correct answer: A
Rationale: Patients should rest and avoid normal activities for a short period after arthroscopy to allow healing and prevent swelling, which could worsen with early activity. Elevation and icing are recommended post-procedure to reduce swelling and pain. Instructing the patient to resume normal activities within 12 hours could lead to increased swelling and delayed healing. Reporting severe pain is crucial as it could indicate a complication. Therefore, the correct instruction is not to resume normal activities immediately after arthroscopy.
2. What is the primary function of surfactant in the lungs?
- A. Reduce surface tension
- B. Enhance oxygen absorption
- C. Facilitate carbon dioxide release
- D. Increase lung volume
Correct answer: A
Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.
3. The nurse is performing a psychosocial assessment on an adolescent aged 14. Which emotional response is typical during early adolescence?
- A. Frequent anger
- B. Cooperativeness
- C. Moodiness
- D. Combativeness
Correct answer: C
Rationale: Moodiness is a typical emotional response during early adolescence. Hormonal changes and developmental challenges contribute to this behavior. While anger and combativeness can also be present during adolescence, they are not as consistently typical as moodiness. Cooperativeness, on the other hand, is a trait more commonly associated with later stages of development and maturity, rather than early adolescence.
4. Which of the following components of nutrition has a primary function of helping with tissue growth and repair?
- A. Vitamin D
- B. Vitamin E
- C. Protein
- D. Fat
Correct answer: C
Rationale: Protein is the correct answer as it is essential for tissue growth and repair. Proteins are composed of amino acids, the building blocks of body tissues. While vitamins D and E have important roles in the body, they are not primarily responsible for tissue growth and repair. Fats are crucial for various bodily functions, like providing energy, but they are not the primary component involved in tissue growth and repair.
5. In which type of cardiomyopathy does septal involvement occur?
- A. Congestive
- B. Dilated
- C. Hypertrophic
- D. Restrictive
Correct answer: C
Rationale: Septal involvement is a characteristic feature of hypertrophic cardiomyopathy, where the septal wall of the heart thickens. This thickening can obstruct blood flow out of the heart, leading to complications such as arrhythmias and heart failure. This differentiates it from other types of cardiomyopathy. In congestive cardiomyopathy (choice A), the heart's chambers become enlarged and weakened, but there is no specific mention of septal involvement. Dilated cardiomyopathy (choice B) involves dilation and impaired contraction of the heart chambers, not specifically septal thickening. Restrictive cardiomyopathy (choice D) is characterized by stiffening of the heart muscle, affecting its ability to fill properly, without direct involvement of the septum.
