Nursing Elites

1. Mr. B is recovering from a surgical procedure that was performed four days ago. The nurse's assessment finds this client coughing up rust-colored sputum; his respiratory rate is 28/minute with expiratory grunting, and his lung sounds have coarse crackles on auscultation. Which of the following conditions is the most likely cause of these symptoms?

• A. Tuberculosis
• B. Pulmonary edema
• C. Pneumonia
• D. Histoplasmosis

Correct answer: C

Rationale: In this scenario, the client's presentation of coughing up rust-colored sputum, increased respiratory rate, expiratory grunting, and coarse crackles on lung auscultation suggests the development of pneumonia. Pneumonia is characterized by lung tissue inflammation or infection, often caused by various organisms. Symptoms may include productive cough, dyspnea, and abnormal breath sounds. Tuberculosis (Choice A) typically presents with a chronic cough, weight loss, and night sweats and is less likely in this acute post-operative setting. Pulmonary edema (Choice B) is characterized by pink, frothy sputum, crackles throughout the lungs, and typically occurs in the context of heart failure. Histoplasmosis (Choice D) is a fungal infection that usually presents with flu-like symptoms and is less likely to manifest with the specific respiratory findings described in this case.

2. In children suspected to have a diagnosis of diabetes, which one of the following complaints would be most likely to prompt parents to take their school-age child for evaluation?

• A. Polyphagia
• B. Dehydration
• C. Bedwetting
• D. Weight loss

Correct answer: C

Rationale: The correct answer is 'Bedwetting.' One of the initial symptoms of type 1 diabetes in children is bedwetting. Parents are likely to notice bedwetting in a school-age child, prompting them to seek evaluation. Polyphagia (excessive hunger) and weight loss are also common symptoms of diabetes but may not be as readily noticeable to parents compared to bedwetting. Dehydration is a consequence of diabetes rather than an early symptom that would prompt parents for evaluation.

3. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

• A. Diarrhea and Vomiting
• B. Dizziness and Drowsiness
• C. Metallic taste
• D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.

4. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

5. A home care nurse instructs the mother of a 5-year-old child with lactose intolerance about dietary measures for her child. The nurse should tell the mother that it is necessary to provide which dietary supplement in the child's diet?

• A. Fats
• B. Zinc
• C. Protein
• D. Calcium

Correct answer: D

Rationale: In lactose intolerance, the inability to digest lactose, the sugar in dairy products, can lead to calcium deficiency if dairy products are removed from the diet. Calcium is crucial for bone health and other bodily functions, so alternative calcium sources like fortified non-dairy milks or leafy greens must be included to prevent deficiency. While fats and proteins are important nutrients, they are not typically deficient in lactose intolerance. Zinc, although an essential mineral, is not the primary concern in this case.
