A client with gastroesophageal reflux disease (GERD) is being taught about dietary modifications. What should be emphasized?

A. Avoiding spicy and fatty foods

B. Eating small, frequent meals

C. Avoiding meals before bedtime

D. All of the above

Correct Answer: D
Rationale: In managing GERD, dietary modifications play a significant role. Avoiding spicy and fatty foods helps reduce irritation, while eating small, frequent meals prevents overeating, which can trigger reflux. Avoiding meals before bedtime allows for better digestion and reduces the likelihood of acid reflux during the night. Therefore, all of the options (A, B, and C) are crucial in managing GERD symptoms, making choice D the correct answer.

A client with a history of chronic heart failure is admitted with symptoms of dyspnea and fatigue. What initial intervention should the nurse prepare to implement?

• A. Administration of IV diuretics
• B. Oxygen therapy
• C. Bed rest
• D. Dietary consultation

Correct Answer: B
Rationale: The correct initial intervention for a client with chronic heart failure presenting with dyspnea and fatigue is oxygen therapy. Oxygen therapy can help relieve dyspnea and improve oxygen saturation levels, which are crucial in managing heart failure exacerbations. Administering IV diuretics may be necessary later to address fluid overload, but oxygen therapy takes precedence in addressing the immediate respiratory distress. Bed rest and dietary consultation are important aspects of care for heart failure patients, but in this scenario, oxygen therapy is the priority to improve the client's respiratory status.

When teaching a group of school-aged children how to reduce the risk for Lyme disease, which instruction should the camp nurse include?

• A. Wash hands frequently.
• B. Avoid drinking lake water.
• C. Do not share personal products.
• D. Wear long sleeves and pants.

Correct Answer: D
Rationale: The correct answer is 'Wear long sleeves and pants.' This instruction is crucial in reducing the risk of Lyme disease because it helps minimize exposure to ticks that carry the disease. Ticks are commonly found in grassy and wooded areas, so covering up with long sleeves and pants can act as a physical barrier and prevent ticks from attaching to the skin. Choices A, B, and C are not directly related to preventing Lyme disease. Washing hands frequently is important for general hygiene but not specifically for preventing tick bites. Avoiding drinking lake water is more about preventing waterborne illnesses rather than Lyme disease. Not sharing personal products is important for preventing the spread of infections but is not directly related to Lyme disease prevention.

A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct Answer: C
Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

A client with a severe headache is being assessed by a nurse. What should the nurse do first?

• A. Administer pain relief medication
• B. Check the client's blood pressure
• C. Assess for associated symptoms such as nausea or photophobia
• D. Offer a quiet environment

Correct Answer: B
Rationale: When a client presents with a severe headache, the initial action should be to check their blood pressure. This step is crucial as it can help determine if the headache is related to hypertension or other cardiovascular issues. Administering pain relief medication should only be done after assessing the client's vital signs and confirming the cause of the headache. While assessing for associated symptoms like nausea or photophobia is important for a comprehensive evaluation, it should follow checking the blood pressure to address immediate concerns. Offering a quiet environment is indeed beneficial for the client's comfort, but it is not the priority when dealing with a severe headache.
