Nursing Elites

1. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.

2. A 24-year-old female contracts hepatitis from contaminated food. During the acute (icteric) phase of the patient's illness, what would serologic testing most likely reveal?

• A. antibody to hepatitis D (anti-HDV).
• B. hepatitis B surface antigen (HBsAg).
• C. anti-hepatitis A virus immunoglobulin G (anti-HAV IgG).
• D. anti-hepatitis A virus immunoglobulin M (anti-HAV IgM).

Correct answer: D

Rationale: Hepatitis A is primarily transmitted through the oral-fecal route. During the acute phase of hepatitis A, serologic testing typically reveals anti-hepatitis A virus immunoglobulin M (anti-HAV IgM). This antibody appears early in the course of the infection. The presence of anti-HAV IgM indicates an acute infection with hepatitis A. Choices A and B are incorrect as hepatitis D and hepatitis B antigens are not typically associated with acute hepatitis A. Choice C, anti-hepatitis A virus immunoglobulin G (anti-HAV IgG), would indicate a past infection and lifelong immunity, which is not expected during the acute phase of the illness.

3. Which of the following conditions is a contraindication for performing a diagnostic peritoneal lavage?

• A. A client who is 9 weeks pregnant
• B. A client with a femur fracture
• C. A morbidly obese client
• D. A client with hypertension

Correct answer: C

Rationale: Diagnostic peritoneal lavage is contraindicated in morbidly obese clients due to several reasons. Excess body fat in morbidly obese individuals makes it challenging to locate essential landmarks required for the procedure. Additionally, the equipment utilized for the lavage may not be sized appropriately to accommodate an obese individual. Furthermore, morbid obesity places undue stress on the cardiovascular and respiratory systems, increasing the risk of complications when administering anesthetic agents during the procedure. Therefore, performing a diagnostic peritoneal lavage on a morbidly obese client is not recommended. Choice A, a client who is 9 weeks pregnant, is not a contraindication for diagnostic peritoneal lavage. Pregnancy status alone does not preclude the procedure unless there are specific maternal or fetal concerns. Choice B, a client with a femur fracture, is not a contraindication for diagnostic peritoneal lavage. The presence of a femur fracture does not typically affect the ability to perform this diagnostic procedure. Choice D, a client with hypertension, is not a contraindication for diagnostic peritoneal lavage. Hypertension, while a consideration for anesthesia and surgery, does not directly impact the feasibility of performing a diagnostic peritoneal lavage.

4. The nurse is caring for a woman 2 hours after a vaginal delivery. Documentation indicates that the membranes were ruptured for 36 hours prior to delivery. What are the priority nursing diagnoses at this time?

• A. Altered tissue perfusion
• B. Risk for fluid volume deficit
• C. High risk for hemorrhage
• D. Risk for infection

Correct answer: D

Rationale: The correct answer is 'Risk for infection.' When the membranes are ruptured for more than 24 hours prior to birth, there is a significantly increased risk of infection for both the mother and the newborn. Monitoring for signs of infection, such as fever, foul-smelling vaginal discharge, and uterine tenderness, is crucial. Option A, 'Altered tissue perfusion,' is not the priority in this scenario as infection risk takes precedence due to the prolonged rupture of membranes. Option B, 'Risk for fluid volume deficit,' is less of a priority compared to the immediate risk of infection. Option C, 'High risk for hemorrhage,' is not the priority concern at this time based on the information provided.

5. An emergency department nurse is performing an assessment on a child with a suspected diagnosis of intussusception. Which assessment question for the parents will elicit the most specific data related to this disorder?

• A. Does the child have any food allergies?
• B. What do the bowel movements look like?
• C. Has the child eaten any food in the last 24 hours?
• D. Can you describe the type of pain that the child is experiencing?

Correct answer: D

Rationale: The correct answer is asking the parents to describe the type of pain the child is experiencing because a report of severe colicky abdominal pain in a healthy, thriving child between 3 and 17 months of age is the classic presentation of intussusception. Typical behavior includes screaming and drawing the knees up to the chest. This specific question helps in identifying the key symptom of intussusception. Choices A, B, and C are important aspects of a health history but are not specific to the diagnosis of intussusception. Food allergies, bowel movements, and recent food intake are relevant for a comprehensive assessment but do not directly relate to the specific symptoms of intussusception.
