Nursing Elites

1. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

2. 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 involves compressing plaque against the wall of a diseased coronary artery to improve blood flow. It is a minimally invasive procedure performed during a cardiac catheterization to open blockages in the coronary arteries. Surgical repair of a diseased coronary artery refers to procedures like coronary artery bypass grafting (CABG), not PTCA. Placement of an automatic internal cardiac defibrillator is a different intervention used for managing cardiac arrhythmias, not for improving coronary blood flow. A non-invasive radiographic examination of the heart would typically refer to procedures like a cardiac CT scan or an MRI, not PTCA.

3. You are responsible for reviewing the nursing unit's refrigerator. Which of the following drugs, if found inside the fridge, should be removed?

• A. Nadolol (Corgard)
• B. Opened (in-use) Humulin N injection
• C. Urokinase (Kinlytic)
• D. Epoetin alfa IV (Epogen)

Correct answer: A

Rationale: Nadolol (Corgard) should be removed if found inside the fridge because it is supposed to be stored at room temperature between 59 to 86 �F (15 and 30 �C) away from heat, moisture, and light. Storing it in the refrigerator can alter its effectiveness and stability. Option B, the opened Humulin N injection, should not be stored in the refrigerator as it is an in-use product and can remain at room temperature for a certain period as per manufacturer guidelines. Option C, Urokinase (Kinlytic), and Option D, Epoetin alfa IV (Epogen), do not require refrigeration and can be stored at room temperature. Therefore, Nadolol (Corgard) is the drug that should be removed from the fridge.

4. The parents of a newborn have been told that their child was born with bladder exstrophy, and the parents ask the nurse about this condition. Which explanation, given by the parents, indicates understanding of this condition?

• A. ''It's a hereditary disorder that occurs in every other generation.''
• B. ''It is caused by the use of medications taken by the mother during pregnancy.''
• C. ''It is a condition in which the urinary bladder is abnormally located in the pelvic cavity.''
• D. ''It's an extrusion of the urinary bladder to the outside of the body through a defect in the lower abdominal wall.''

Correct answer: D

Rationale: Bladder exstrophy is a congenital anomaly characterized by the extrusion of the urinary bladder to the outside of the body through a defect in the lower abdominal wall. The cause of bladder exstrophy is not precisely known, but it is believed to be due to a developmental abnormality during embryogenesis. The condition is more common in male newborns. Choice A is incorrect as bladder exstrophy is not a hereditary disorder that occurs in every other generation. Choice B is incorrect as bladder exstrophy is not caused by medications taken by the mother during pregnancy. Choice C is incorrect as it describes the condition inaccurately; it is not just an abnormal location of the bladder in the pelvic cavity, but rather an extrusion of the bladder outside the body through a defect in the lower abdominal wall.

5. The nurse reviews the record of a child who is suspected to have glomerulonephritis. Which statement by the child's parent should the nurse expect that is associated with this diagnosis?

• A. ''His pediatrician said his kidneys are working well.''
• B. ''I noticed his urine was the color of cola lately.''
• C. ''I'm so glad they didn't find any protein in his urine.''
• D. ''The nurse who admitted my child said his blood pressure was low.''

Correct answer: B

Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Gross hematuria, resulting in dark, smoky, cola-colored, or brown-colored urine, is a classic symptom of glomerulonephritis. Blood urea nitrogen levels and serum creatinine levels may be elevated, indicating that kidney function is compromised. A mild to moderate elevation in protein in the urine is associated with glomerulonephritis. Hypertension is also common because of fluid volume overload secondary to the kidneys not working properly. Therefore, the parent's statement about noticing cola-colored urine aligns with the expected symptom in glomerulonephritis. The other options are less indicative of glomerulonephritis: choice A indicates normal kidney function, choice C mentions absence of protein in the urine (which is not expected in glomerulonephritis), and choice D talks about low blood pressure (hypertension is more common in glomerulonephritis).
