Nursing Elites

1. Septic, anaphylactic, and neurogenic shock are all categorized as:

• A. Hypovolemic shock
• B. Cardiogenic shock
• C. Distributive shock
• D. Obstructive shock

Correct answer: C

Rationale: Septic, anaphylactic, and neurogenic shock are all types of distributive shock. Distributive shock is characterized by a decrease in systemic vascular resistance, leading to poor tissue perfusion. Septic shock is caused by severe infection, anaphylactic shock is an extreme allergic reaction, and neurogenic shock results from damage to the nervous system. Hypovolemic shock (Choice A) is characterized by a decrease in intravascular volume, cardiogenic shock (Choice B) is due to heart failure, and obstructive shock (Choice D) results from obstruction of blood flow. Therefore, the correct categorization for septic, anaphylactic, and neurogenic shock is distributive shock.

2. A client is brought into the emergency room where the physician suspects that he has cardiac tamponade. Based on this diagnosis, the nurse would expect to see which of the following signs or symptoms in this client?

• A. Fever, fatigue, malaise
• B. Hypotension and distended neck veins
• C. Cough and hemoptysis
• D. Numbness and tingling in the extremities

Correct answer: B

Rationale: Cardiac tamponade occurs when fluid or blood accumulates in the pericardium, preventing the heart from contracting properly. This leads to decreased cardiac output and is considered a medical emergency. Classic signs of cardiac tamponade include hypotension (low blood pressure) and distended neck veins due to the increased pressure around the heart. These signs result from the compromised ability of the heart to pump effectively. Choices A, C, and D are not typically associated with cardiac tamponade. Fever, fatigue, and malaise are non-specific symptoms that can be seen in various conditions. Cough and hemoptysis are more commonly associated with respiratory conditions, while numbness and tingling in the extremities are neurological symptoms not typically seen in cardiac tamponade.

3. The child with hemolytic-uremic syndrome is anuric and will undergo peritoneal dialysis. Which measure should the nurse implement?

• A. Restrict fluids as prescribed.
• B. Care for the arteriovenous fistula.
• C. Encourage foods high in potassium.
• D. Administer analgesics as prescribed.

Correct answer: A

Rationale: In hemolytic-uremic syndrome, often associated with bacterial toxins and viruses, acute kidney injury occurs in children, leading to symptoms like anemia, thrombocytopenia, renal injury, and CNS symptoms. For an anuric child with hemolytic-uremic syndrome undergoing peritoneal dialysis, fluid restriction is vital to prevent fluid overload. Pain management is not directly related to hemolytic-uremic syndrome. Foods high in potassium should be limited, not encouraged, due to impaired kidney function. Peritoneal dialysis does not involve an arteriovenous fistula, which is specific to hemodialysis.

4. In a 24-year-old woman, the term used to define uterine bleeding in which there is no menstruation is:

• A. Oligomenorrhea
• B. Amenorrhea
• C. Menorrhagia
• D. Metrorrhagia

Correct answer: B

Rationale: Amenorrhea is the correct term for the absence of menstrual periods in a woman of childbearing age. It is typically defined as no menstruation for at least three consecutive cycles or six months. Oligomenorrhea refers to infrequent or irregular menstrual periods rather than complete absence. Menorrhagia is characterized by excessive menstrual bleeding, not the absence of menstruation. Metrorrhagia involves irregular, acyclic bleeding between menstrual periods, which is different from the absence of menstruation.

5. 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.
