This is crucial for the patient's overall experience and can positively impact their recovery. Obtaining preoperative orders (A) is typically the responsibility of the physician. Explaining the surgical procedure (C) is usually done by the surgeon. Providing informed consent (D) involves ensuring the patient understands the risks and benefits of the procedure, which is typically the responsibility of the healthcare provider performing the procedure.

A client has been diagnosed with renal failure and is admitted for dialysis. Which of the ff is the nurse’s responsibility as the client undergone dialysis?
- A. Keeping dialysis supplies in a clean area
- B. Inspecting the catheter insertion site for signs of infection
- C. Weighing the client before and after the procedure
- D. washing hands before and after handling the catheter
Correct Answer: C
Rationale: The correct answer is C: Weighing the client before and after the procedure. This is crucial as it helps monitor fluid removal during dialysis, ensuring the process is effective and safe. Weighing helps determine if the correct amount of fluid has been removed.
A: Keeping dialysis supplies in a clean area is important for infection control but not a direct responsibility during the procedure.
B: Inspecting the catheter insertion site for signs of infection is essential for monitoring the site's health but not a direct responsibility during dialysis.
D: Washing hands before and after handling the catheter is a general infection control measure but not specific to the dialysis procedure itself.
Which of the following is the most critical intervention needed for a client with myxedema coma?
- A. Administering an oral dose of levothyroxine (Synthroid)
- B. Warming the client with a warming blanket
- C. Measuring and recording accurate intake and output
- D. Maintaining a patent airway
Correct Answer: A
Rationale: The correct answer is A: Administering an oral dose of levothyroxine (Synthroid). In myxedema coma, there is severe hypothyroidism leading to altered mental status, hypothermia, and organ failure. Administering levothyroxine is crucial to replace the deficient thyroid hormone rapidly and restore metabolic function. Warming the client (B) is important but secondary to addressing the underlying hormonal imbalance. Measuring intake and output (C) is essential for overall assessment but not the most critical intervention. Maintaining a patent airway (D) is always important in any medical emergency but does not directly address the primary issue of hypothyroidism in myxedema coma.
Which of the ff. statements does the nurse understand is true concerning air conduction of sound in the ear?
- A. It is caused by the vibration of bones in the skull.
- B. It is less efficient than bone conduction.
- C. It is heard longer than bone conduction.
- D. It is caused by transmission of heat through the air.
Correct Answer: B
Rationale: The correct answer is B because air conduction is less efficient than bone conduction due to the sound waves traveling through the air in the ear canal, which can be hindered by factors like blockages or obstructions. This results in a weaker and less clear sound transmission compared to bone conduction, where sound waves are transmitted directly through the bones of the skull, bypassing any potential obstructions in the ear canal.
Incorrect choices:
A: This statement is incorrect as air conduction of sound in the ear is not caused by the vibration of bones in the skull.
C: This statement is incorrect as air conduction is typically heard for a shorter duration than bone conduction.
D: This statement is incorrect as air conduction of sound in the ear is not caused by the transmission of heat through the air, but rather by sound waves traveling through the ear canal.
A client with advanced liver cancer is scheduled for chemotherapy. As part of the chemotherapy regimen, the nurse expects the physician to prescribe:
- A. Fluoxymesterone (Halotestin)
- B. Fluorouracil (5-fluorouracil, 5 FU
- C. Tamoxifen (Nolvadex) [Fluoroplex])
- D. Megestrol (Megace)
Correct Answer: B
Rationale: The correct answer is B: Fluorouracil (5-fluorouracil, 5-FU). Fluorouracil is a commonly used chemotherapy drug for treating advanced liver cancer. It works by inhibiting the growth of cancer cells. This drug is specifically effective in targeting rapidly dividing cells, which is a characteristic of cancer cells. Fluorouracil is often used in combination with other chemotherapy drugs to improve treatment outcomes.
Summary of other choices:
A: Fluoxymesterone (Halotestin) - This is an androgen hormone used to treat certain types of breast cancer, not liver cancer.
C: Tamoxifen (Nolvadex) - This is a hormonal therapy drug used in breast cancer, not liver cancer.
D: Megestrol (Megace) - This is a hormonal therapy drug used for certain types of cancers, but not typically for liver cancer.
Which iron-rich foods should the nurse encourage an anemic client requiring iron therapy to eat?
- A. Shrimp and tomatoes
- B. Cheese and bananas
- C. Lobster and squash
- D. Lamb and peaches
Correct Answer: D
Rationale: The correct answer is D (Lamb and peaches) because lamb is a good source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Peaches are high in vitamin C, which enhances iron absorption. Shrimp and tomatoes (A) have some iron but are not as rich in iron as lamb. Cheese and bananas (B) are not significant sources of iron. Lobster and squash (C) also do not provide as much iron as lamb. Overall, the combination of heme iron from lamb and vitamin C from peaches makes them the most suitable choices for an anemic client requiring iron therapy.
