What is the first medication to give for wheezing due to an allergic reaction?
- A. Albuterol via nebulizer
- B. Cromolyn 20 mg via nebulizer
- C. Methylprednisolone 100 mg IV
- D. Aminophylline 500 mg IV
Correct Answer: A
Rationale: Albuterol is the first-line medication for treating wheezing due to an allergic reaction. Albuterol is a short-acting beta-agonist that helps relieve bronchospasm quickly. Cromolyn is more commonly used for the prevention of asthma symptoms rather than for acute treatment. Methylprednisolone and aminophylline are not the first-line medications for acute wheezing due to an allergic reaction.

A patient with hypokalemia is being monitored. What should the nurse assess for?
- A. Muscle weakness
- B. Flattened T waves
- C. Checking deep tendon reflexes
- D. Seizures
Correct Answer: A
Rationale: Corrected Question: A patient with hypokalemia is being monitored. What should the nurse assess for?
Corrected Choice A: Muscle weakness
Corrected Choice B: Flattened T waves
Corrected Choice C: Checking deep tendon reflexes
Corrected Choice D: Seizures
Rationale: Hypokalemia is associated with muscle weakness due to the effect of low potassium levels on muscle function. Flattened T waves on an ECG are characteristic of hypokalemia but are not a direct assessment for the patient's condition. Checking deep tendon reflexes and seizures are not primary symptoms associated with hypokalemia, making them less relevant for monitoring a patient with this electrolyte imbalance.
What should be done when continuous bubbling is observed in the chest tube water seal chamber?
- A. Tighten the connections of the chest tube system
- B. Replace the chest tube system
- C. Clamp the chest tube
- D. Continue to monitor the chest tube
Correct Answer: A
Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate action is to tighten the connections of the chest tube system. This may resolve an air leak that is causing the continuous bubbling. Option B, replacing the chest tube system, is not the initial step to take and is considered more invasive. Clamping the chest tube (option C) can lead to complications and should not be done unless instructed by a healthcare provider. Continuing to monitor the chest tube (option D) without taking any corrective action may delay necessary interventions.
What is an escharotomy and why is it performed?
- A. A surgical incision made to improve circulation in burn injuries
- B. A procedure to remove dead tissue from a wound
- C. A procedure to remove excess fluid from the lungs
- D. A procedure to relieve pain from burns
Correct Answer: A
Rationale: An escharotomy is a surgical procedure involving an incision through the eschar (dead tissue) to relieve pressure in burn injuries. It is performed to improve circulation to the affected area, prevent further damage, and restore blood flow. Choice B is incorrect because an escharotomy is not primarily focused on removing dead tissue but rather on relieving pressure. Choice C is incorrect as it describes a procedure related to pulmonary issues, not burn injuries. Choice D is incorrect because while pain relief may be a result of an escharotomy, it is not the primary purpose of the procedure.
What are the expected symptoms in a patient with a thrombotic stroke?
- A. Gradual loss of function on one side of the body
- B. Sudden loss of consciousness
- C. Severe headache and confusion
- D. Loss of sensation in the affected limb
Correct Answer: A
Rationale: A thrombotic stroke typically presents with a gradual loss of function on one side of the body. This gradual onset distinguishes it from a hemorrhagic stroke, which often manifests with sudden and severe symptoms like loss of consciousness (choice B), severe headache and confusion (choice C), or loss of sensation in the affected limb (choice D). Therefore, choices B, C, and D are not typically associated with thrombotic strokes.
What are the manifestations of osteomyelitis?
- A. Localized pain, swelling, erythema
- B. Elevated white blood cells
- C. Elevated calcium levels
- D. Low potassium levels
Correct Answer: A
Rationale: Osteomyelitis often manifests as localized pain, swelling, and erythema due to infection in the bone. These symptoms are characteristic of inflammation and infection in the bone tissue. Elevated white blood cells (Choice B) may be present as part of the body's immune response to the infection but are not specific manifestations of osteomyelitis. Elevated calcium levels (Choice C) and low potassium levels (Choice D) are not typically associated with osteomyelitis.
