A nurse is teaching a client who has peptic ulcer disease about preventing exacerbations. Which of the following instructions should the nurse include?

Correct Answer: B

Rationale: The correct answer is B: Limit alcohol consumption. Alcohol consumption can aggravate peptic ulcer disease by increasing gastric acid secretion, potentially leading to exacerbations. Choices A, C, and D are incorrect. Choice A is not recommended because antacids containing magnesium can interfere with other medications or conditions the client may have. Choice C is a good recommendation; however, it is not the priority instruction for preventing exacerbations. Choice D is also incorrect as caffeine can stimulate gastric acid secretion, which can worsen peptic ulcer disease.

Correct Answer: A

Rationale: Corrected Rationale: Bradycardia is a common sign of hypoglycemia due to the body's response to low blood sugar. During hypoglycemia, the body releases epinephrine, leading to sympathetic nervous system activation. This can result in bradycardia as a compensatory mechanism to preserve glucose for vital organs such as the brain. Tachycardia, hypotension, and diaphoresis are more commonly associated with hypoglycemia when it progresses to severe stages and the body's compensatory mechanisms are overwhelmed.

Correct Answer: A

Rationale: To assess a patient for potential deep vein thrombosis (DVT), healthcare professionals should look for unilateral leg swelling. This is a classic sign of DVT. While encouraging early mobilization is generally beneficial for preventing DVT, it is not a method of assessment. Checking for calf tenderness is also relevant but not as specific as unilateral leg swelling. Observing for redness and warmth can be signs of inflammation but are not as specific to DVT as unilateral leg swelling.

Correct Answer: A

Rationale: The correct signs of hypoglycemia include shakiness or tremors, sweating, and hunger. These symptoms indicate low blood sugar levels. Confusion or irritability are more associated with severe hypoglycemia, while the immediate treatment for hypoglycemia involves providing a source of glucose to raise blood sugar levels quickly.

Correct Answer: A

Rationale: Administering oxygen is crucial in managing a patient experiencing respiratory distress. Oxygen therapy helps to improve oxygen levels in the blood, supporting vital organ functions. While monitoring airway patency is important, administering oxygen takes precedence in ensuring the patient receives an adequate oxygen supply. Providing bronchodilators may be beneficial in certain respiratory conditions, but the immediate priority in distress is to address oxygenation. Calling for assistance is essential, but the immediate intervention to support the patient's respiratory function is administering oxygen.
