Nursing Elites

1. A 93-year-old female with a history of Alzheimer's Disease gets admitted to an Alzheimer's unit. The patient has exhibited signs of increased confusion and limited stability with gait. Moreover, the patient is refusing to use a w/c. Which of the following is the most appropriate course of action for the nurse?

• A. Recommend the patient remain in her room at all times.
• B. Recommend family members bring pictures to the patient's room.
• C. Recommend a speech therapy consult to the doctor.
• D. Recommend the patient attempt to walk pushing the w/c for safety.

Correct answer: B

Rationale: For a 93-year-old female with Alzheimer's Disease exhibiting signs of increased confusion and limited stability with gait, recommending family members to bring pictures to the patient's room is the most appropriate course of action. Visual stimulation in the form of pictures may help decrease signs of confusion and provide comfort to the patient. Option A is incorrect as isolating the patient in her room at all times may worsen her condition by further limiting stimulation and interaction. Option C is incorrect as speech therapy may not directly address the current issues of confusion and gait instability. Option D is incorrect as pushing a wheelchair may not be safe for the patient if she is refusing to use it, potentially leading to falls or further distress.

2. For a client with suspected appendicitis, where should the nurse expect to find abdominal tenderness?

• A. upper right
• B. upper left
• C. lower right
• D. lower left

Correct answer: C

Rationale: The correct answer is C: lower right. Abdominal tenderness in the lower-right quadrant is a classic symptom of appendicitis. This tenderness is known as McBurney's point, which is located in the lower-right quadrant of the abdomen. Choices A, B, and D are incorrect because the tenderness associated with appendicitis is typically localized to the lower-right quadrant.

3. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

• A. It protects the bacteria from antibiotic and immunologic destruction.
• B. Glycocalyx neutralizes the antibiotic, rendering it ineffective.
• C. It competes with the antibiotic for binding sites on the microbe.
• D. Glycocalyx provides nutrients for microbial growth.

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.

4. A healthcare professional is reviewing a patient's arterial blood gas values. Which of the following conditions apply under the following values? pH- 7.49 Bicarbonate ion 24 mEq/dl PaCO2 - 31 mmHg PaO2 - 52 mmHg FiO2 - 0.22

• A. respiratory acidosis
• B. respiratory alkalosis
• C. metabolic acidosis
• D. metabolic alkalosis

Correct answer: B

Rationale: The given blood gas values indicate respiratory alkalosis. A high pH and low PaCO2 level are consistent with respiratory alkalosis. In this scenario, no compensation for the alkalosis is noted, ruling out metabolic acidosis or alkalosis. Metabolic conditions would usually involve changes in bicarbonate levels, which remain within the normal range in this case.

5. What is the drug of choice for herpes simplex virus 1, herpes simplex virus 2, and varicella-zoster virus?

• A. HIV.
• B. HSV 1, HSV 2, and VZV.
• C. CMV
• D. Influenza A viruses.

Correct answer: B

Rationale: Acyclovir (Zovirax) is the drug of choice for herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), and varicella-zoster virus (VZV) infections. It works by inhibiting viral DNA replication. Acyclovir is excreted unchanged in the urine, so caution is needed in renal impairment. Choice A, HIV, is incorrect as acyclovir is not the drug of choice for HIV. Choice C, CMV, is incorrect as acyclovir is not the preferred treatment for cytomegalovirus (CMV) infections. Choice D, Influenza A viruses, is incorrect as acyclovir is not used to treat influenza viruses.
