Nursing Elites

1. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is:

• A. Surgical repair of a diseased coronary artery
• B. Placement of an automatic internal cardiac defibrillator
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow
• D. Non-invasive radiographic examination of the heart

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.

2. A patient is found unconscious in their room with rhythmic jerking of all four extremities and heavy foaming at the mouth. The patient was on seizure precautions with bedrails up and padded. What is the priority action for the nurse to take?

• A. Administer Lorazepam (Ativan)
• B. Turn the patient to his/her side
• C. Call the physician
• D. Suction the patient

Correct answer: B

Rationale: The nurse's priority action should be to turn the patient to his/her side. This position helps maintain an open airway and prevents aspiration of secretions or vomitus. Administering Lorazepam (Ativan) without ensuring a clear airway could lead to further complications. Calling the physician is important, but immediate interventions to protect the airway take precedence. Suctioning the patient may be necessary but should not be the initial action; positioning for airway protection is the priority.

3. Mr. C is brought to the hospital with severe burns over 45% of his body. His heart rate is 124 bpm and thready, BP 84/46, respirations 24/minute and shallow. He is apprehensive and restless. Which of the following types of shock is Mr. C at highest risk for?

• A. Septic shock
• B. Hypovolemic shock
• C. Neurogenic shock
• D. Cardiogenic shock

Correct answer: B

Rationale: Mr. C, who has severe burns over 45% of his body, is at highest risk for hypovolemic shock. Burns lead to a loss of plasma volume, reducing the circulating fluid volume and impairing perfusion to vital organs and extremities. In this scenario, the signs of shock, such as increased heart rate, low blood pressure, shallow respirations, and restlessness, indicate a state of hypovolemic shock due to significant fluid loss. Septic shock (choice A) is primarily caused by severe infections, neurogenic shock (choice C) results from spinal cord injuries, and cardiogenic shock (choice D) stems from heart failure. However, in this case, the presentation aligns most closely with hypovolemic shock due to the extensive burn injury and its effects on fluid volume and perfusion.

4. 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.

5. A child is hospitalized because of persistent vomiting. The nurse should monitor the child closely for which problem?

• A. Diarrhea
• B. Metabolic acidosis
• C. Metabolic alkalosis
• D. Hyperactive bowel sounds

Correct answer: C

Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.
