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.

A client with a diagnosis of trigeminal neuralgia is started on a regimen of carbamazepine. The nurse provides instructions to the client about the medication. What statement by the client indicates that the client understands the instructions?
- A. I will report a fever or sore throat to my doctor.
- B. Some joint pain is expected and is nothing to worry about.
- C. I must brush my teeth frequently to avoid damage to my gums.
- D. My urine may turn red in color, but this is nothing to be concerned about.
Correct Answer: A
Rationale: Carbamazepine is an anticonvulsant medication and is also used to alleviate the pain associated with trigeminal neuralgia. Agranulocytosis is an adverse effect of carbamazepine, and it places the client at risk for infection. If the client develops a fever or a sore throat, the primary health care provider should be notified. Unusual bruising and bleeding are also adverse effects of the medication, and they need to be reported to the primary health care provider if they occur.
A client is preparing to undergo a cystoscopy for stones. Which of the following statements indicates that the client understands the procedure?
- A. I better drink a lot of fluid now because I won't be able to after the test.
- B. I will probably see a little blood when I urinate.
- C. I will be able to go home after 3 days in the hospital.
- D. I won't need any pain medicine; this probably will not hurt.
Correct Answer: B
Rationale: The correct answer is, 'I will probably see a little blood when I urinate.' During a cystoscopy, a scope is inserted into the client's bladder to inspect structures or remove objects like stones. This procedure is usually performed under local or general anesthesia. It is common for clients to experience a small amount of blood in their urine (hematuria) or have pink-colored urine after the procedure. The other choices are incorrect because drinking a lot of fluid before the test, staying in the hospital for 3 days, and assuming no pain will be experienced are not accurate statements related to a cystoscopy procedure.
Mr. N is a client who entered the hospital with a diagnosis of diabetic ketoacidosis. The nurse enters his room to check his vital signs and finds him breathing at a rate of 32 times per minute; his respirations are deep and regular. Which type of respiratory pattern is Mr. N most likely exhibiting?
- A. Kussmaul respirations
- B. Cheyne-Stokes respirations
- C. Biot's respirations
- D. Cluster breathing
Correct Answer: A
Rationale: Mr. N is most likely exhibiting Kussmaul respirations. Kussmaul respirations are a form of hyperventilation associated with conditions like metabolic acidosis. They are characterized by rapid, regular, and deep breathing. This type of respiratory pattern helps the body compensate for metabolic acidosis by attempting to blow off excess carbon dioxide. This pattern is different from Cheyne-Stokes respirations (choice B), which are characterized by alternating periods of deep, rapid breathing followed by apnea. Biot's respirations (choice C) are characterized by groups of quick, shallow inspirations followed by irregular periods of apnea, and Cluster breathing (choice D) involves clusters of breaths followed by periods of apnea, often seen in patients with brain injury or neurological conditions.
A child is seen in the health care clinic, and testing for human immunodeficiency virus (HIV) is performed because of the child's exposure to HIV infection. Which home care instruction should the nurse provide to the parents of the child?
- A. Avoid sharing toothbrushes.
- B. Avoid all immunizations until the diagnosis is established.
- C. Wipe up any blood spills with a rag, and allow them to air-dry.
- D. Wash your hands with half-strength bleach if they come in contact with the child's blood.
Correct Answer: A
Rationale: Parents should avoid sharing toothbrushes to prevent potential HIV transmission through blood or bodily fluids. Immunizations should be kept up to date to protect the child. Blood spills should be cleaned with a paper towel, followed by soap and water, then a bleach solution, not just a rag and air-drying. Washing hands with soap and water is sufficient; bleach is too caustic for skin.
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.
