Question 1 of 9

Mr Santos is placed on seizure precaution. Which of the following would be contraindicated?

Correct Answer: A

Rationale: The correct answer is A: Obtain his oral temperature. Seizure precautions typically include avoiding putting objects in the mouth to prevent injury during a seizure. Taking an oral temperature involves placing an object in the mouth, which could pose a risk if a seizure occurs. Choices B, C, and D are not contraindicated as they do not directly involve potential risks during a seizure. Allowing the patient to wear his own clothing, encouraging personal hygiene, and promoting mobility are safe practices that do not increase the risk of harm during a seizure.

Question 2 of 9

Then the drug is stopped. When should treatment resume?

Correct Answer: A

Rationale: The correct answer is A because the drug should be resumed when the WBC count falls to 5,000mm3 to ensure the client's safety and efficacy of treatment. This criterion indicates that the client's immune system has recovered sufficiently to tolerate the drug. Choices B, C, and D are incorrect because they do not directly correlate with the client's immune system recovery, which is crucial for drug tolerance. Choice B focuses on the rise in WBC count, not the fall to a specific level. Choice C is related to a cosmetic side effect, not clinical readiness. Choice D is unrelated to immune system recovery.

Question 3 of 9

If a client with increased pressure (ICP) demonstrates decorticate posturing, the nurse will observe:

Correct Answer: A

Rationale: The correct answer is A because decorticate posturing is characterized by flexion of both upper and lower extremities. This occurs due to damage to the cerebral hemispheres, resulting in abnormal muscle contractions. Choice B describes decerebrate posturing, which is associated with extension of elbows and knees. Choice C is incorrect as it describes abnormal posturing seen in other conditions. Choice D is also incorrect as it describes a different type of abnormal posturing.

Question 4 of 9

A home care nurse assesses for disease complications in a client with bone cancer. The nurse knows that bone cancer may cause which electrolyte disturbance?

Correct Answer: C

Rationale: The correct answer is C: Hypercalcemia. In bone cancer, there can be excessive release of calcium from the bones, leading to elevated blood calcium levels. This can result in various complications such as kidney stones, cardiac arrhythmias, and weakness. Hyperkalemia (choice A) is not commonly associated with bone cancer. Hyponatremia (choice B) is more commonly seen in conditions like heart failure or kidney disease. Hypomagnesemia (choice D) is not a common electrolyte disturbance in bone cancer.

Question 5 of 9

A 32 y.o. male patient is admitted to a medical unit with a diagnosis of Guillain-Barre Syndrome. His legs are weak, and he is unable to walk without assistance. Which of the ff. is most likely responsible for this syndrome?

Correct Answer: D

Rationale: The correct answer is D: Autoimmune reaction. Guillain-Barre Syndrome is an autoimmune disorder where the immune system mistakenly attacks the peripheral nerves, leading to muscle weakness and paralysis. This is supported by the patient's presentation of weakness in the legs. Bacterial infection (A) can trigger Guillain-Barre Syndrome, but it is not the root cause. High-fat diet (B) and heredity (C) are not associated with the development of this syndrome. In summary, autoimmune reaction is the primary mechanism underlying Guillain-Barre Syndrome, resulting in the patient's muscle weakness and inability to walk.

Question 6 of 9

A patient verbalizes a low pain level of 2 out of 10 but exhibits extreme facial grimacing while moving around in bed. What is the nurse’s initial action in response to these observations?

Correct Answer: C

Rationale: The correct initial action is to choose C: Ask the patient about the facial grimacing with movement. This is important as the patient's non-verbal cues (facial grimacing) contradict their verbal pain report. By directly addressing the discrepancy, the nurse can gather more accurate information about the patient's pain experience and potentially identify any underlying issues causing the discrepancy. Proceeding to the next patient's room (A) without addressing the discrepancy would neglect the patient's needs. Assuming the patient does not want pain medicine (B) based solely on the verbal report without further assessment is premature. Administering pain medication (D) without clarifying the situation may lead to inappropriate or ineffective treatment. Therefore, option C is the most appropriate initial action to ensure comprehensive and individualized patient care.

Question 7 of 9

In a client who has human immunodeficiency virus (HIV) infection, CD4+ levels are measured to determine the:

Correct Answer: B

Rationale: Step-by-step rationale: 1. CD4+ cells are a type of white blood cell crucial for immune function. 2. HIV targets and destroys CD4+ cells, leading to immune system damage. 3. Measuring CD4+ levels helps determine the extent of this damage. 4. Therefore, the correct answer is B. Summary: A: Presence of opportunistic infections - CD4+ levels indirectly affect susceptibility, but not measured for this purpose. C: Level of the viral load - Measured separately from CD4+ levels. D: Resistance to antigens - CD4+ levels do not directly indicate resistance.

Question 8 of 9

A client with suspected lung cancer is scheduled for thoracentesis as part of the diagnostic workup. The nurse reviews the client’s history for conditions that might contraindicate this procedure. Which condition is a contraindication for thoracentesis?

Correct Answer: D

Rationale: The correct answer is D: A bleeding disorder. Thoracentesis involves inserting a needle into the pleural space to remove fluid. A bleeding disorder increases the risk of excessive bleeding during the procedure. This can lead to complications such as hematoma formation, pneumothorax, or even life-threatening bleeding. It is crucial to assess and address bleeding disorders before performing thoracentesis to ensure the safety of the client. A: A seizure disorder is not a contraindication for thoracentesis unless uncontrolled seizures could compromise the safety of the procedure. B: Anemia alone is not a contraindication for thoracentesis, as it does not directly increase the risk of complications during the procedure. C: Chronic obstructive pulmonary disease is not a contraindication for thoracentesis unless it is severe and compromises the client's ability to tolerate the procedure.

Question 9 of 9

A brain abscess is a collection of pus within the substance of the brain and is caused by:

Correct Answer: D

Rationale: The correct answer is D because a brain abscess can be caused by direct invasion of the brain, spread of infection by other organs, and spread of infection from nearby sites. Direct invasion can occur from trauma or surgery, while infections from other organs like the lungs or heart can travel through the bloodstream to the brain. Infections from nearby sites such as the sinuses or ears can also spread to the brain. Therefore, all of these mechanisms can lead to the formation of a brain abscess. Choices A, B, and C alone do not encompass all the possible causes of a brain abscess, making D the correct comprehensive answer.
