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.

When obtaining a health history and physical assessment for a 36-year-old female patient with possible multiple sclerosis (MS), the nurse should
- A. assess for the presence of chest pain.
- B. inquire about urinary tract problems.
- C. inspect the skin for rashes or discoloration.
- D. ask the patient about any increase in libido.
Correct Answer: B
Rationale: When assessing a patient for possible multiple sclerosis (MS), it is important to inquire about urinary tract problems as they are common symptoms of the condition, such as incontinence or retention. Chest pain is not typically associated with MS, so assessing for its presence is not a priority. Inspecting the skin for rashes or discoloration is not a typical manifestation of MS. Additionally, a decrease in libido, rather than an increase, is more commonly seen in patients with MS. Therefore, the most appropriate action for the nurse in this scenario is to inquire about urinary tract problems.
The nurse administers prescribed therapies for a patient with cor pulmonale and right-sided heart failure. Which assessment would best evaluate the effectiveness of the therapies?
- A. Observe for distended neck veins.
- B. Auscultate for crackles in the lungs.
- C. Palpate for heaves or thrills over the heart.
- D. Review hemoglobin and hematocrit values.
Correct Answer: A
Rationale: To evaluate the effectiveness of therapies for cor pulmonale and right-sided heart failure, observing for distended neck veins would be the most appropriate assessment. Cor pulmonale is characterized by right ventricular failure due to pulmonary hypertension, leading to clinical manifestations such as peripheral edema, jugular venous distention, and right upper-quadrant abdominal tenderness. These signs indicate increased central venous pressure and right heart strain, which can be assessed by observing for distended neck veins. Auscultating for crackles in the lungs is more indicative of left-sided heart failure rather than right-sided heart failure. Heaves or thrills over the heart are not typically associated with cor pulmonale. Reviewing hemoglobin and hematocrit values may show elevations due to chronic hypoxemia and polycythemia in cor pulmonale, but these values alone do not directly evaluate the immediate effectiveness of the prescribed therapies on the patient's condition.
What action will the nurse plan to take for a 40-year-old patient with multiple sclerosis (MS) who has urinary retention caused by a flaccid bladder?
- A. Decrease the patient's evening fluid intake.
- B. Teach the patient how to use the Cred method.
- C. Suggest the use of adult incontinence briefs for nighttime only.
- D. Assist the patient to the commode every 2 hours during the day.
Correct Answer: B
Rationale: For a 40-year-old patient with multiple sclerosis experiencing urinary retention due to a flaccid bladder, teaching the Cred method is the appropriate action. The Cred method involves applying manual pressure over the bladder to aid in bladder emptying. Decreasing fluid intake is not the correct approach as it will not address the underlying issue of bladder emptying and may lead to dehydration and urinary tract infections. Using adult incontinence briefs only addresses the symptom of incontinence without addressing the bladder emptying problem. Assisting the patient to the commode every 2 hours does not actively address the issue of improving bladder emptying as effectively as teaching the Cred method.
The nurse develops a plan of care to prevent aspiration in a high-risk patient. Which nursing action will be most effective?
- A. Turn and reposition immobile patients at least every 2 hours.
- B. Place patients with altered consciousness in side-lying positions.
- C. Monitor for respiratory symptoms in immunosuppressed patients.
- D. Insert nasogastric tube for feedings in patients with swallowing problems.
Correct Answer: B
Rationale: To prevent aspiration in a high-risk patient, the most effective nursing action is to place patients with altered consciousness in side-lying positions. This position helps decrease the risk of aspiration as it prevents pooling of secretions and facilitates drainage. Turning and repositioning immobile patients every 2 hours is essential for preventing pressure ulcers and improving circulation but does not directly address the risk of aspiration. Monitoring respiratory symptoms in immunosuppressed patients is crucial to detect pneumonia early, but it does not directly prevent aspiration. Inserting a nasogastric tube for feedings in patients with swallowing problems may be necessary for nutritional support but does not address the risk of aspiration directly. Patients at high risk for aspiration include those with altered consciousness, difficulty swallowing, and those with nasogastric intubation, among others. Placing patients with altered consciousness in a side-lying position is a key intervention to reduce the risk of aspiration in this population. Other high-risk groups for aspiration include those who are seriously ill, have poor dentition, or are on acid-reducing medications.
A patient who was admitted the previous day with pneumonia complains of a sharp pain of 7 (based on a 0 to 10 scale) whenever taking a deep breath. Which action will the nurse take next?
- A. Auscultate breath sounds.
- B. Administer PRN morphine.
- C. Have the patient cough forcefully.
- D. Notify the patient's healthcare provider.
Correct Answer: A
Rationale: The patient's complaint of sharp pain when taking a deep breath is concerning for pleurisy or pleural effusion. The nurse should auscultate breath sounds to assess for a pleural friction rub or decreased breath sounds, which could indicate these conditions. It is crucial to gather assessment data before initiating any pain medications. Asking the patient to cough forcefully may exacerbate the pain and should be avoided until further assessment. Contacting the healthcare provider should be based on the assessment findings; therefore, it is premature to notify the provider without conducting a thorough assessment first.
