Nursing Elites

1. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?

• A. Decreased cardiac output can cause hypoxia to the brain
• B. Mental status changes may be a side effect of the patient's medication
• C. Mitral regurgitation is a complication associated with some neurological disorders
• D. The patient may be confused about his diagnosis

Correct answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

2. A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?

• A. Anesthesia reaction
• B. Hyperglycemia
• C. Hypoglycemia
• D. Diabetic ketoacidosis

Correct answer: C

Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.

3. Which intervention will the nurse include in the plan of care for a patient diagnosed with a lung abscess?

• A. Teach the patient to avoid using over-the-counter expectorants.
• B. Assist the patient with chest physiotherapy and postural drainage.
• C. Notify the healthcare provider immediately regarding any bloody or foul-smelling sputum.
• D. Teach about the necessity of prolonged antibiotic therapy after discharge from the hospital.

Correct answer: D

Rationale: For a patient diagnosed with a lung abscess, the priority intervention is to educate them about the importance of prolonged antibiotic therapy post-hospital discharge. Long-term antibiotic treatment is crucial for eradicating the infecting organisms in a lung abscess. Chest physiotherapy and postural drainage are not recommended for lung abscess as they can potentially spread the infection. While foul-smelling and bloody sputum are common in lung abscess, immediate notification to the healthcare provider is essential. Avoiding the use of over-the-counter expectorants is not necessary, as expectorants can be used to facilitate coughing and clearing of secretions in this condition.

4. A patient asks a nurse administering blood how long red blood cells live in the body. What is the correct response?

• A. The life span of RBC is 45 days
• B. The life span of RBC is 60 days
• C. The life span of RBC is 90 days
• D. The life span of RBC is 120 days

Correct answer: D

Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.

5. A mother brings her 5-week-old infant to the health care clinic and tells the nurse that the child has been vomiting after meals. The mother reports that the vomiting is becoming more frequent and forceful. The nurse suspects pyloric stenosis and asks the mother which assessment question to elicit data specific to this condition?

• A. Are the stools ribbon-like, and is the infant eating poorly?
• B. Does the infant suddenly become pale, begin to cry, and draw the legs up to the chest?
• C. Does the vomit contain sour, undigested food without bile, and is the infant constipated?
• D. Does the infant cry loudly and continuously during the evening hours but nurses or takes formula well?

Correct answer: C

Rationale: Vomiting undigested food that is not bile stained and constipation are classic symptoms of pyloric stenosis. Stools that are ribbon-like and a child who is eating poorly are signs of congenital megacolon (Hirschsprung's disease). An infant who suddenly becomes pale, cries out, and draws the legs up to the chest is demonstrating physical signs of intussusception. Crying during the evening hours, appearing to be in pain, eating well, and gaining weight are clinical manifestations of colic.
