1. 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.

2. An elderly client seems confused and reports the onset of nausea, dysuria, and urgency with incontinence. Which action should the nurse implement?

A. Auscultate for renal bruits
B. Obtain a clean catch mid-stream specimen
C. Use a dipstick to measure for urinary ketones
D. Begin to strain the client's urine

Correct answer: B

Rationale: This elderly client is presenting symptoms consistent with a urinary tract infection (UTI), such as confusion, nausea, dysuria, urgency, and incontinence. The best course of action for the nurse is to obtain a clean catch mid-stream specimen. This specimen will help identify the causative agent of the UTI, allowing for targeted treatment with an appropriate anti-infective agent. Auscultating for renal bruits (Choice A) is not indicated in this scenario as the client's symptoms point towards a UTI rather than a renal issue. Using a dipstick to measure for urinary ketones (Choice C) is not relevant in the context of UTI symptoms. Beginning to strain the client's urine (Choice D) would not address the need to identify the causative agent for targeted treatment.

3. The healthcare provider explains through an interpreter the risks and benefits of a scheduled surgical procedure to a non-English speaking female client. The client gives verbal consent, and the healthcare provider leaves, instructing the nurse to witness the signature on the consent form. The client and the interpreter then speak together in the foreign language for an additional 2 minutes until the interpreter concludes, 'She says it is OK.' What action should the nurse take next?

A. Ask for a full explanation from the interpreter of the witnessed discussion.
B. Have the client sign the consent form.
C. Document the conversation and witness the consent.
D. Ask the client directly if she has any questions.

Correct answer: A

Rationale: The correct action for the nurse to take next is to ask for a full explanation from the interpreter of the witnessed discussion. Verbal consent is not sufficient; it is crucial to ensure that the client fully comprehends the risks and benefits of the surgical procedure. By asking the interpreter to provide a detailed explanation of the discussion, the nurse can confirm that the client has given informed consent. Having the client sign the consent form (Choice B) without ensuring complete understanding may lead to potential misunderstandings. Documenting the conversation and witnessing the consent (Choice C) is not enough to guarantee the client's comprehension. Asking the client directly if she has any questions (Choice D) may not be effective if language barriers persist.

4. The unit clerk reports to the charge nurse that a healthcare provider has written several prescriptions that are illegible and it appears the healthcare provider used several unapproved abbreviations in the prescriptions. What actions should the charge nurse take?

A. Call the healthcare provider who wrote the prescription
B. Attempt to clarify the prescriptions with the pharmacist
C. Administer the medications as prescribed
D. Ask another healthcare provider for clarification

Correct answer: A

Rationale: The correct action for the charge nurse to take is to call the healthcare provider who wrote the illegible prescriptions. It is crucial to clarify illegible prescriptions directly with the provider to ensure patient safety and prevent medication errors. Option B, attempting to clarify with the pharmacist, may lead to misinterpretation and is not the recommended first step. Administering the medications as prescribed without clarity can jeopardize patient safety, making option C incorrect. Asking another healthcare provider for clarification (option D) may not be effective as the responsibility lies with the provider who wrote the prescription.

5. Which class of drugs is the only source of a cure for septic shock?

A. Antihypertensives
B. Anti-infectives
C. Antihistamines
D. Anticholesteremics

Correct answer: B

Rationale: The correct answer is B: Anti-infectives. Anti-infective agents, such as antibiotics, are essential in treating septic shock as they can eliminate bacteria and halt the progression of the condition by stopping the production of endotoxins. Antihypertensives (Choice A) are used to lower blood pressure, antihistamines (Choice C) are used to treat allergic reactions, and anticholesteremics (Choice D) are used to lower cholesterol levels. However, none of these drug classes directly address the bacterial infection that underlies septic shock.
