Nursing Elites

1. 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.

2. A 58-year-old client is being tested for rheumatoid arthritis. Her physician orders an erythrocyte sedimentation rate (ESR). Which of the following results is most likely to be associated with arthritis?

• A. 5 mm/hr
• B. 12 mm/hr
• C. 28 mm/hr
• D. 40 mm/hr

Correct answer: D

Rationale: The erythrocyte sedimentation rate (ESR) measures levels of inflammation in the body. Elevated ESR levels are commonly seen in autoimmune conditions like rheumatoid arthritis due to the presence of inflammation. In women over 50 years old, a normal ESR is typically below 30 mm/hr. Therefore, a result of 40 mm/hr is more indicative of arthritis in a 58-year-old individual. Choices A, B, and C are below the normal ESR range for a woman of this age and would not be as strongly associated with arthritis.

3. The chain of infection includes the ________________.

• A. germ, agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host
• B. active natural, active artificial, passive natural, and passive artificial
• C. opportunism, weakness, immunity, and colonization
• D. intrinsic, extrinsic, internal, and external transmission

Correct answer: A

Rationale: The chain, or cycle, of infection includes the germ (microorganism), agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host. This sequence describes how infections are passed from one person to another. Choice B is incorrect because it refers to types of immunity, not components of the chain of infection. Choice C is also incorrect as it lists terms unrelated to the chain of infection. Choice D is incorrect as it describes transmission types, not components of the chain of infection. Understanding the chain of infection is crucial in preventing the spread of infections by breaking one or more links in the chain, such as interrupting the mode of transmission through proper hand hygiene.

4. Which of the following conditions may warrant a serum creatinine level?

• A. Rhabdomyolysis
• B. Digitalis toxicity
• C. Glomerulonephritis
• D. All answers are correct

Correct answer: D

Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.

5. A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?

• A. Contain histamine and provide protection during allergic reactions
• B. Are involved in phagocytosis
• C. Provide protection and immunity against foreign substances
• D. Carry hemoglobin and oxygen to body tissues

Correct answer: C

Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue. Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes. Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages. Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.
