1. A nurse is caring for a patient with an infection. Which laboratory result is most important to monitor?

A. White blood cell count (WBC)
B. C-reactive protein (CRP)
C. Erythrocyte sedimentation rate (ESR)
D. Hemoglobin and hematocrit levels

Correct answer: A

Rationale: The correct answer is A: White blood cell count (WBC). Monitoring the white blood cell count is crucial when caring for a patient with an infection as it helps assess the body's response to the infection. An elevated white blood cell count often indicates an active infection or inflammation, while a decreasing count may signal improvement or potential complications. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are nonspecific markers of inflammation and not as specific to monitoring infection progression as the white blood cell count. Hemoglobin and hematocrit levels are important for assessing oxygen-carrying capacity and blood volume, but they are not the primary indicators for monitoring infection.

2. A nurse is monitoring an older adult female client who had a myocardial infarction (MI) for the development of an acute kidney injury (AKI). Which of the following findings should the nurse identify as indicating an increased risk of AKI?

A. Magnesium 2.0 mEq/L
B. Blood urea nitrogen (BUN) 20 mg/dL
C. Serum Osmolality 290 mOsm/kg H2O
D. Serum creatinine 1.8 mg/dL

Correct answer: D

Rationale: An elevated serum creatinine level (1.8 mg/dL) is a significant indicator of potential kidney impairment. In acute kidney injury (AKI), serum creatinine levels rise due to decreased kidney function, reflecting the kidneys' inability to effectively filter waste from the blood. Magnesium level, BUN, and serum osmolality are not direct indicators of kidney function or risk of AKI. Magnesium levels are more related to electrolyte balance, BUN can be affected by factors other than kidney function, and serum osmolality reflects the concentration of solutes in the blood, not specifically kidney function.

3. What should be done to manage a patient with contact precautions?

A. Wear a mask, gown, and gloves for all patient interactions.
B. Ensure that visitors wear protective equipment.
C. Dedicate all patient care equipment to that patient.
D. Disinfect shared equipment before use.

Correct answer: C

Rationale: When managing a patient with contact precautions, it is essential to dedicate all patient care equipment to that specific patient. This practice helps minimize the risk of spreading infections to other patients. Choice A, wearing protective gear for all patient interactions, is a general precaution but not specific to managing a patient with contact precautions. Choice B, ensuring visitors wear protective equipment, is important for infection control but not directly related to managing the patient with contact precautions. Choice D, disinfecting shared equipment before use, is a good practice for infection control in general but does not address the specific needs of a patient under contact precautions.

4. A client is prescribed 1g of potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g in 250 ml of dextrose 5%. What rate should the nurse set the IV pump to run at?

A. 40 ml/hr
B. 42 ml/hr
C. 44 ml/hr
D. 46 ml/hr

Correct answer: B

Rationale: To calculate the IV rate, divide the total volume by the total time in hours. In this case, 1 g in 250 ml is to be infused over 6 hours. Therefore, 250 ml / 6 hr = 42 ml/hr. This means the IV pump should be set to run at 42 ml/hr. Choices A, C, and D are incorrect as they do not accurately calculate the infusion rate based on the provided information.

5. What is a key characteristic of Illness Anxiety Disorder?

A. Excessive focus on minor symptoms without medical evidence of illness
B. The need for consistent reassurance from healthcare professionals
C. Compulsive behavior to avoid physical illness
D. Development of avoidance behaviors to reduce anxiety

Correct answer: A

Rationale: The correct answer is A: "Excessive focus on minor symptoms without medical evidence of illness." Illness Anxiety Disorder, formerly known as hypochondriasis, is characterized by a preoccupation with having a serious illness despite no medical evidence to support the presence of an illness. Individuals with this disorder often interpret normal bodily sensations as signs of severe illness. Choice B is incorrect because while individuals with Illness Anxiety Disorder may seek reassurance from healthcare professionals, the excessive focus on minor symptoms is the key characteristic. Choice C is incorrect as compulsive behaviors to avoid physical illness are more characteristic of illnesses like Obsessive-Compulsive Disorder. Choice D is incorrect as the development of avoidance behaviors to reduce anxiety is more commonly seen in conditions like specific phobias or social anxiety disorder.
