Nursing Elites

1. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

• A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
• B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
• C. The client should lie flat on their back for a specific period following the procedure.
• D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

2. A client with schizophrenia is taking loxapine. Which of the following findings should the nurse identify as the most important to report?

• A. Spasms of the tongue and face
• B. Orthostatic hypotension
• C. Dry mouth
• D. Increased appetite

Correct answer: A

Rationale: Spasms of the muscles of the tongue, face, neck, and back are indicative of acute dystonia, an extrapyramidal manifestation associated with loxapine use. Acute dystonia is a serious condition that can lead to airway obstruction and respiratory compromise. Therefore, the nurse should prioritize reporting this finding to prevent potential harm to the client. Orthostatic hypotension, dry mouth, and increased appetite are common side effects of antipsychotic medications but are not as immediately life-threatening as acute dystonia. Monitoring and managing these side effects are essential for the client's overall well-being, but they do not pose the same level of urgency as addressing acute dystonia.

3. What is involved in obtaining informed consent?

• A. An explanation of the reasons for the procedure
• B. A signature on a form indicating the client agrees to the procedure
• C. A statement affirming liability if complications arise during the procedure
• D. Both A and C

Correct answer: A

Rationale: Informed consent involves providing the client with an explanation of the reasons for the procedure, the potential risks, benefits, and available alternatives. It is essential for the healthcare provider to ensure that the client understands the information provided before agreeing to the procedure. While obtaining a signature on a consent form is part of the process, it is not the sole indicator of informed consent. Option C, which mentions liability statements, is incorrect as informed consent focuses on ensuring the client understands the procedure, not on affirming liability. Therefore, the correct answer is the explanation of the reasons for the procedure.

4. A client is diagnosed with schizophrenia. A physician orders haloperidol (Haldol) 50 mg bid, benztropine (Cogentin) 1 mg prn, and zolpidem (Ambien) 10 mg HS. Which client behavior would warrant the nurse to administer benztropine?

• A. Tactile hallucinations
• B. Tardive dyskinesia
• C. Restlessness and muscle rigidity
• D. Reports of hearing disturbing voices

Correct answer: C

Rationale: Benztropine (Cogentin) is an anticholinergic medication used to treat extrapyramidal symptoms, such as restlessness and muscle rigidity, which are common side effects of antipsychotic medications like haloperidol. Tactile hallucinations and reports of hearing disturbing voices are symptoms of schizophrenia that would typically be addressed by the antipsychotic medication (haloperidol) itself. Tardive dyskinesia, a potential side effect of long-term antipsychotic use, would require discontinuation of the antipsychotic medication rather than administration of benztropine.

5. Mr. G has been admitted to the hospital with a head injury after a 12-foot fall. Which of the following nursing interventions is most appropriate when monitoring intracranial pressure?

• A. Administer hypotonic solutions
• B. Keep the head of the bed elevated
• C. Increase the client's core body temperature to 99.9 degrees
• D. Administer corticosteroids as ordered

Correct answer: D

Rationale: Administering corticosteroids as ordered is appropriate when monitoring intracranial pressure in clients at risk of increased pressure to reduce brain tissue swelling. Elevating the head of the bed helps in managing intracranial pressure by promoting venous drainage. Administering hypertonic solutions is used to reduce brain edema and control intracranial pressure. Increasing the client's core body temperature is not recommended as it can exacerbate brain injury. Corticosteroids are not routinely used for all head injuries but may be indicated in specific cases, such as certain types of brain injuries where swelling needs to be controlled.
