Most physical problems that occur during peritoneal or hemodialysis are related to which phenomenon that may result from
- A. nausea and vomiting due to too rapid removal of fluid
- B. movement of red blood cells across the dialyzing membrane
- C. movement of glucose from the dialyzing solution into the blood
- D. water intoxication from excessive fluid removal
Correct Answer: A
Rationale: The correct answer is A: nausea and vomiting due to too rapid removal of fluid during peritoneal or hemodialysis. This is because rapid removal of fluid can lead to electrolyte imbalances and changes in blood pressure, causing nausea and vomiting.
Choice B is incorrect because movement of red blood cells across the dialyzing membrane is not a common physical problem during dialysis.
Choice C is incorrect because movement of glucose from the dialyzing solution into the blood is not typically associated with physical problems during dialysis.
Choice D is incorrect because water intoxication from excessive fluid removal can occur, but it is not the most common physical problem during dialysis.

You are providing care for a patient with reflex urinary incontinence. Which action is appropriately delegated to the new LPN/LVN?
- A. Teach the patient bladder emptying by the Credé method.
- B. Demonstrate how to perform intermittent self-catheterization.
- C. Discuss the side effects of bethanechol chloride (Urecholine).
- D. Reinforce the importance of proper handwashing to prevent infection.
Correct Answer: B
Rationale: The correct answer is B because demonstrating how to perform intermittent self-catheterization is within the scope of practice for an LPN/LVN. This task involves a specific skill set that can be taught and supervised by the LPN/LVN. It is essential for managing reflex urinary incontinence and maintaining bladder function. Choices A, C, and D are incorrect because teaching the patient bladder emptying by the Credé method (A) and discussing the side effects of bethanechol chloride (C) are tasks that require a higher level of nursing education and knowledge. Reinforcing the importance of proper handwashing (D) is a basic nursing task that can be performed by a nursing assistant or other unlicensed assistive personnel.
A function of the kidney is to
- A. produce angiotensin
- B. remove microorganisms from the blood
- C. remove aged blood from the blood
- D. regulate blood ionic composition
Correct Answer: D
Rationale: The correct answer is D: regulate blood ionic composition. The kidneys help maintain the body's electrolyte balance by regulating the levels of ions such as sodium, potassium, and calcium in the blood. This is crucial for proper nerve and muscle function, pH balance, and overall homeostasis.
Explanation for why the other choices are incorrect:
A: The production of angiotensin is primarily done by the liver and lungs, not the kidneys.
B: While the kidneys help filter out waste and toxins, they do not specifically target microorganisms in the blood.
C: Removing aged blood from the blood is not a function of the kidneys; this task is mainly carried out by the spleen and liver.
In summary, the kidney's main function is to regulate blood ionic composition to maintain overall bodily functions, making choice D the correct answer.
When assessing a newborn infant's genitalia, the nurse notices that the genitalia are somewhat engorged. The labia majora are swollen, the clitoris looks large, and the hymen is thick. The vaginal opening is difficult to visualize. The infant's mother states that she is worried about the labia being swollen. The nurse should reply:
- A. This is a normal finding in newborns and should resolve within a few weeks.
- B. This finding could indicate an abnormality and may need to be evaluated by a physician.
- C. We will need to have estrogen levels evaluated to ensure that they are within normal limits.
- D. We will need to keep close watch over the next few days to see if the genitalia decrease in size.
Correct Answer: A
Rationale: Step 1: Neonatal genital engorgement is a common finding due to maternal hormones.
Step 2: Maternal hormones can cause swelling of the labia majora, clitoris, and thickening of the hymen.
Step 3: This physiological phenomenon typically resolves within a few weeks post-birth.
Step 4: The nurse should reassure the mother that this is a normal finding in newborns.
Summary: Choice A is correct because it aligns with the normal physiological process, while the other options suggest unnecessary interventions or monitoring that are not indicated in this situation.
Combivir is a combination therapy used to treat HIV and AIDS include which of the following drugs?
- A. Lamivudine and stavudine
- B. Lamivudine and zidovudine
- C. Abacavir and zidovudine
- D. Abacavir and stavudine
Correct Answer: B
Rationale: The correct answer is B: Lamivudine and zidovudine. Combivir is a combination therapy that contains these two drugs, which are commonly used together to treat HIV and AIDS. Lamivudine and zidovudine work synergistically to inhibit viral replication by targeting different stages of the HIV life cycle. Lamivudine is a nucleoside reverse transcriptase inhibitor (NRTI) that blocks the action of the enzyme reverse transcriptase, while zidovudine is also an NRTI that interferes with viral DNA synthesis. This combination helps reduce the viral load and improve the immune response in patients.
Incorrect Choices:
A: Lamivudine and stavudine - Stavudine is not part of the Combivir combination therapy.
C: Abacavir and zidovudine - Abacavir is not part of the Combivir combination therapy.
D: Abacavir and stavudine
Antiviral agents that is/ are active against cytomegalovirus (CMV) include which of the following?
- A. Ganciclovir
- B. Foscarnet
- C. Acyclovir
- D. (a) and (b) are correct
Correct Answer: D
Rationale: The correct answer is D because both Ganciclovir and Foscarnet are active against cytomegalovirus (CMV). Ganciclovir works by inhibiting viral DNA polymerase, while Foscarnet inhibits viral DNA polymerase and reverse transcriptase. Acyclovir, on the other hand, is not effective against CMV as it primarily targets herpes simplex virus and varicella-zoster virus. Therefore, choices A and B are correct for CMV treatment, making option D the correct answer.
