What does the dialysate for PD routinely contain?
- A. Calcium in a lower concentration than in the blood
- B. Sodium in a higher concentration than in the blood
- C. Dextrose in a higher concentration than in the blood
- D. Electrolytes in an equal concentration to that of the blood
Correct Answer: C
Rationale: Correct Answer: C - Dextrose in a higher concentration than in the blood
Rationale:
1. Dextrose in PD dialysate helps to create an osmotic gradient for fluid removal.
2. Higher dextrose concentration ensures effective ultrafiltration.
3. Dextrose is the main osmotic agent used in PD.
4. A higher concentration of dextrose in the dialysate aids in waste removal.
Summary:
A: Incorrect - Calcium concentration in dialysate is similar to blood to avoid imbalance.
B: Incorrect - Sodium concentration is lower in dialysate to prevent sodium loading.
D: Incorrect - Electrolyte concentration in dialysate is tailored to patient needs, not equal to blood.

Generally, the changes normally associated with menopause occur because the cells in the reproductive tract are:
- A. Aging.
- B. Becoming fibrous.
- C. Estrogen dependent.
- D. Able to respond to estrogen.
Correct Answer: C
Rationale: The correct answer is C: Estrogen dependent. During menopause, the changes in the reproductive tract are primarily due to the decline in estrogen levels. Estrogen plays a crucial role in regulating the menstrual cycle and maintaining the health of the reproductive tissues. As estrogen levels decrease, it leads to various symptoms and changes associated with menopause. Choices A and B are incorrect as they do not directly relate to the hormonal changes that occur during menopause. Choice D is incorrect because during menopause, the cells in the reproductive tract become less responsive to estrogen due to the decline in estrogen levels.
Which of the following viruses is most susceptible to acyclovir?: *
- A. Herpes simplex Type 1 virus
- B. Herpes simplex Type 2 virus
- C. Varicell
- D. zoster virus
Correct Answer: A
Rationale: Acyclovir is a nucleoside analog that inhibits viral DNA replication by targeting viral DNA polymerase. Herpes simplex Type 1 virus is most susceptible to acyclovir because it is a DNA virus that requires viral DNA polymerase for replication. The drug is selectively activated by viral thymidine kinase in infected cells, leading to its antiviral activity. Herpes simplex Type 2, Varicella zoster, and other viruses do not possess the same susceptibility to acyclovir due to differences in their replication mechanisms.
Which of the following would be examples of foods selected to lower the pH of urine?
- A. Milk
- B. Tea
- C. Apples
- D. Meat
Correct Answer: C
Rationale: The correct answer is C: Apples. Apples are acidic in nature, which can help lower the pH of urine. Consuming acidic foods can make the urine more acidic. Milk is alkaline, so it would raise the pH of urine. Tea can vary in acidity, but generally it is not chosen to lower urine pH. Meat is also not acidic and would not contribute to lowering urine pH. So, apples are the most suitable choice for lowering urine pH among the options provided.
A nurse is examining a 35-year-old female patient. During the health history, the nurse notices that she has had two term pregnancies, and both babies were delivered vaginally. During the internal examination, the nurse observes that the cervical os is a horizontal slit with some healed lacerations and that the cervix has some nabothian cysts that are small, smooth, and yellow. In addition, the nurse notices that the cervical surface is granular and red, especially around the os. Finally, the nurse notices the presence of stringy, opaque, odorless secretions. Which of these findings are abnormal?
- A. Nabothian cysts are present.
- B. The cervical os is a horizontal slit.
- C. The cervical surface is granular and red.
- D. Stringy, opaque secretions are present.
Correct Answer: C
Rationale: The correct answer is C: The cervical surface is granular and red. This finding indicates inflammation or infection, as a healthy cervix should appear smooth and pink. The presence of granular and red surface could suggest cervicitis or another underlying issue that needs further evaluation or treatment.
A: Nabothian cysts are present - This is a normal finding and does not indicate any abnormality or concern.
B: The cervical os is a horizontal slit - This is a normal anatomical variation and does not indicate any abnormality.
D: Stringy, opaque secretions are present - This can be a normal finding depending on the phase of the menstrual cycle and does not necessarily indicate an abnormality.
Dialysis is used to treat patients with:
- A. Acute glomerulonephritis.
- B. Renal failure.
- C. Nephrolithiasis.
- D. Pyelonephritis.
Correct Answer: B
Rationale: Step-by-step rationale:
1. Renal failure is a condition where the kidneys are unable to adequately filter waste from the blood.
2. Dialysis is a treatment used to perform the functions of the kidneys in patients with renal failure.
3. Dialysis helps remove excess waste, fluids, and toxins from the blood, maintaining proper electrolyte balance.
4. Patients with acute glomerulonephritis, nephrolithiasis, and pyelonephritis may not require dialysis as their conditions do not directly affect kidney function to the extent that renal failure does.
Summary:
- A: Acute glomerulonephritis does not always lead to renal failure requiring dialysis.
- C: Nephrolithiasis is the formation of kidney stones and may not always require dialysis.
- D: Pyelonephritis is a kidney infection and may not necessarily lead to renal failure requiring dialysis.
