Nokea
The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?
- A. Serum creatinine of 1.5 mg/dL
- B. Serum sodium of 136 mEq/L
- C. Serum potassium of 5.5 mEq/L
- D. Hemoglobin of 12 g/dL
Correct Answer: C
Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.

In assessing a client 48 hours following a fracture, the nurse observes ecchymosis at the fracture site and recognizes that hematoma formation at the bone fragment site has occurred. What action should the nurse implement?
- A. Document the extent of the bruising in the medical record.
- B. Apply a cold compress to the area.
- C. Elevate the affected limb.
- D. Notify the healthcare provider.
Correct Answer: A
Rationale: After observing ecchymosis at the fracture site, indicating hematoma formation, the nurse's priority is to document the extent of the bruising in the medical record. This documentation helps track the client's condition, aids in treatment planning, and serves as a baseline for monitoring changes. Applying a cold compress (choice B) may be contraindicated due to the risk of vasoconstriction and potential tissue damage. Elevating the affected limb (choice C) can be beneficial for reducing swelling in some cases, but documenting the bruising is the immediate concern. Notifying the healthcare provider (choice D) is not necessary at this stage unless there are other concerning symptoms or complications beyond the hematoma formation.
The nurse is administering an IV medication to a client with a history of anaphylaxis. Which intervention is most important for the nurse to implement?
- A. Stay with the client throughout the infusion.
- B. Keep emergency resuscitation equipment at the bedside.
- C. Obtain the client's allergy history.
- D. Ask the client about past allergic reactions to medications.
Correct Answer: B
Rationale: Keeping emergency resuscitation equipment at the bedside is crucial in case the client experiences anaphylaxis during the infusion. While staying with the client throughout the infusion (Choice A) is important, having immediate access to emergency equipment takes priority in this situation. Obtaining the client's allergy history (Choice C) and asking about past allergic reactions to medications (Choice D) are relevant but do not address the immediate need for emergency intervention in case of anaphylaxis.
The nurse is caring for a client with a chest tube following a pneumothorax. Which finding requires immediate intervention?
- A. Oxygen saturation of 94%
- B. Crepitus around the insertion site
- C. Subcutaneous emphysema
- D. Drainage of 50 ml per hour
Correct Answer: C
Rationale: Subcutaneous emphysema is the most critical finding requiring immediate intervention in a client with a chest tube following a pneumothorax. It may indicate a pneumothorax recurrence or air leak, which can lead to respiratory compromise. Oxygen saturation of 94% is slightly low but may not require immediate intervention. Crepitus around the insertion site can be a normal finding post-procedure. Drainage of 50 ml per hour is within the expected range for a chest tube output and does not indicate an immediate concern.
The nurse observes an adolescent client preparing to administer a prescribed corticosteroid medication using a metered dose inhaler. What action should the nurse take?
- A. Remind the client to hold their breath after inhaling the medication
- B. Confirm that the client has correctly shaken the inhaler
- C. Affirm that the client has correctly positioned the inhaler
- D. Ask the client if they have a spacer to use for this medication
Correct Answer: A
Rationale: Corrected Rationale: Reminding the client to hold their breath after inhaling the medication is crucial as it helps ensure the medication is absorbed into the lungs. Option B is incorrect because shaking the inhaler is not directly related to the client's inhalation technique. Option C is incorrect as correct positioning of the inhaler is important but not the immediate action needed in this situation. Option D is incorrect as asking about the spacer is not the most relevant action to take at this moment.
A client with urticaria due to environmental allergies is taking diphenhydramine. Which complaint should the nurse identify as a side effect of the OTC medication?
- A. Nausea and indigestion.
- B. Hypersalivation.
- C. Eyelid and facial twitching.
- D. Increased appetite.
Correct Answer: A
Rationale: The correct answer is A: Nausea and indigestion. Diphenhydramine, an antihistamine, commonly causes gastrointestinal side effects such as nausea and indigestion. This medication can have anticholinergic effects, leading to these symptoms. Choices B, C, and D are incorrect because hypersalivation, eyelid and facial twitching, and increased appetite are not typically associated with diphenhydramine use.
