1. Which type of cells secrete insulin?
- A. alpha cells
- B. beta cells
- C. CD4 cells
- D. helper cells
Correct answer: B
Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.
2. What should the nurse do while caring for a client with an eating disorder?
- A. Encourage the client to cook for others
- B. Weigh the client daily and keep a journal
- C. Restrict access to mirrors
- D. Monitor food intake and behavior for one hour after meals
Correct answer: D
Rationale: The correct answer is to monitor food intake and behavior for one hour after meals. This is crucial in caring for a client with an eating disorder as it helps in assessing any immediate risks related to the disorder. Option A is incorrect as it may trigger additional stress for the client and distract from the main focus of managing the disorder. Option B, weighing the client daily, could lead to an unhealthy focus on weight and potentially worsen the client's mental health. Option C, restricting access to mirrors, although it may be beneficial for body image concerns, does not directly address the core issue of monitoring food intake and behavior, which is essential in managing eating disorders.
3. The client is scheduled for surgical repair of a detached retina. What is the most likely preoperative nursing diagnosis for this client?
- A. Anxiety related to loss of vision and potential failure to regain vision.
- B. Deficient knowledge (preoperative and postoperative activities) related to lack of information.
- C. Acute pain related to tissue injury and decreased circulation to the eye.
- D. Risk for infection related to the eye injury.
Correct answer: A
Rationale: The correct preoperative nursing diagnosis for a client scheduled for surgical repair of a detached retina is 'Anxiety related to loss of vision and potential failure to regain vision.' A client facing the threat of permanent blindness due to a detached retina is likely to experience anxiety. Addressing this anxiety is crucial before providing education, as severe anxiety can hinder the client's ability to absorb new information. The nurse should offer emotional support, encourage the client to express concerns, and clarify any misconceptions. Acute pain is not a typical symptom of a detached retina, and the risk of infection preoperatively is minimal, making choices C and D less relevant in this scenario.
4. In conducting a community health fair for a group of middle-aged citizens, which statement should the nurse emphasize in reducing the risk of coronary heart disease?
- A. Participate in at least 30 minutes of moderate physical activity 3 to 5 days per week.
- B. Engage in an aerobic exercise class every day.
- C. Limit your alcohol intake to a moderate level.
- D. The best way to lose weight is to follow a balanced diet.
Correct answer: B
Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.
5. What is the best nursing diagnosis for a client with newly diagnosed Diabetes Mellitus?
- A. Impaired Skin Integrity
- B. Knowledge Deficit: New Diabetes Diagnosis
- C. Alteration in Nutrition: More than Body Requirements
- D. Fluid Volume Deficit
Correct answer: B
Rationale: The correct answer is 'Knowledge Deficit: New Diabetes Diagnosis.' Newly diagnosed diabetics require education on their disease, medications, glucose testing, insulin injections, foot care, and sick-day plans. Choices A and D aim to prevent issues that do not currently exist for the client. Choice C, 'Alteration in Nutrition: More than Body Requirements,' is not the priority diagnosis for a newly diagnosed diabetic. While nutritional adjustments may be required for type I or type II diabetes, providing knowledge and education takes precedence at this stage.
