A nurse is caring for a patient with diabetes. Which of the following symptoms should the nurse recognize as a sign of hypoglycemia?

Correct Answer: C

Rationale: The correct answer is C: Tremors and dizziness. Hypoglycemia is characterized by low blood sugar levels. Tremors and dizziness are common symptoms due to the brain not receiving enough glucose for energy. Tachycardia and nausea (choice A) are more indicative of hyperglycemia. Polyuria and polydipsia (choice B) are classic symptoms of hyperglycemia in diabetes. Weight loss and fatigue (choice D) are not specific symptoms of hypoglycemia.

Correct Answer: B

Rationale: The correct answer is B: Respiratory failure. Patients with COPD have impaired lung function, making them at risk for respiratory failure due to inadequate oxygenation. This can occur due to exacerbation of COPD, infections, or other factors. Monitoring for signs of respiratory distress is crucial. A: Pneumonia - While patients with COPD are at higher risk for pneumonia due to impaired lung function, respiratory failure is a more immediate and critical complication to monitor for in this scenario. C: Hypoglycemia - COPD does not directly increase the risk of hypoglycemia, so monitoring for this complication is not a priority in this case. D: Hypertension - Although some patients with COPD may have hypertension, it is not a common complication directly related to COPD. Monitoring for respiratory failure is more essential in this situation.

Correct Answer: B

Rationale: Step 1: The patient has a history of hypertension and diabetes, putting them at risk for cardiovascular complications. Step 2: Among the choices, stroke is a common complication associated with uncontrolled hypertension and diabetes. Step 3: Monitoring for signs of stroke is crucial to prevent serious consequences in this patient population. Step 4: Hyperglycemia (A) is a common complication of diabetes, but it is not directly related to the patient's hypertension. Step 5: Hypokalemia (C) is an electrolyte imbalance that can occur in some conditions but is not as directly linked to the patient's history. Step 6: Hypoglycemia (D) is a potential complication in diabetic patients but is not as common as hyperglycemia and is not directly related to hypertension.

Correct Answer: B

Rationale: Step 1: The review of systems is a systematic approach to assessing the patient's overall health. Step 2: It gathers information about symptoms across different body systems. Step 3: This information helps identify potential health risks and guide health promotion practices. Step 4: Choice B is correct as it aligns with the purpose of the review of systems. Summary: - Choice A is incorrect because it focuses on physical findings only, not the comprehensive assessment. - Choice C is incorrect as the review of systems is not primarily for teaching medical terms. - Choice D is incorrect as it does not provide enough information for diagnosing specific medical problems.

Correct Answer: B

Rationale: The correct answer is B: Administer an antiemetic as prescribed. Administering an antiemetic helps alleviate nausea and vomiting, providing relief to the patient. This action is based on evidence-based practice and helps improve the patient's comfort and well-being. Offering clear fluids immediately (choice A) may exacerbate nausea. Waiting for the nausea to subside on its own (choice C) may prolong the patient's discomfort. Assessing vital signs (choice D) is important but may not directly address the immediate symptom of nausea.

Correct Answer: B

Rationale: The correct answer is B: Increased wheezing and shortness of breath. During an asthma exacerbation, bronchial airways become inflamed and narrowed, leading to increased wheezing and shortness of breath. This is a classic sign of worsening asthma. Other choices are incorrect because: A) Decreased work of breathing is not expected in an asthma exacerbation as the patient usually struggles to breathe. C) Improved oxygen saturation is unlikely as airway obstruction can lead to decreased oxygen levels. D) Decreased sputum production is not a typical sign of asthma exacerbation; in fact, increased sputum production may occur due to airway inflammation.

Correct Answer: B

Rationale: The correct answer is B because encouraging deep breathing and coughing exercises helps to improve lung function and prevent complications in pneumonia. This intervention can help clear secretions, improve oxygenation, and prevent respiratory distress. Administering antibiotics (choice A) is important but not the priority for immediate patient care. Providing pain relief (choice C) is essential but addressing respiratory function is more critical. Monitoring oxygen saturation levels (choice D) is necessary, but promoting lung function through exercises takes precedence.

Correct Answer: C

Rationale: The correct answer is C: Linea nigra. This is a common finding during pregnancy due to hormonal changes causing hyperpigmentation on the abdomen. The other choices are incorrect because keratosis refers to a skin condition characterized by rough, scaly patches; melasma is a condition causing dark patches on the skin, often due to hormonal changes; and linea gravida is not a recognized term in dermatology. Therefore, based on the context of the patient being pregnant and presenting with hyperpigmentation on her face, the most likely finding would be Linea nigra, a dark line that runs from the navel to the pubic bone during pregnancy.

Correct Answer: C

Rationale: The correct answer is C. This statement indicates the need for further education because it suggests the patient plans to stop taking medication once blood pressure is normal, which can lead to hypertension returning. Monitoring blood pressure, taking medication as prescribed, and decreasing sodium intake are all appropriate actions for managing hypertension. Stopping medication abruptly can be dangerous and should only be done under a healthcare provider's guidance.
