Inhalation of carbogen for short period is recommended:
- A. To stimulate respiration
- B. To dilate blood vessels
- C. To dislodge the blood clot
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D. Carbogen is a gas mixture of carbon dioxide and oxygen. Inhaling carbogen can stimulate respiration due to increased oxygen levels and carbon dioxide acting as a respiratory stimulant. It can also dilate blood vessels, enhancing oxygen delivery to tissues. Additionally, carbogen can help dislodge blood clots by improving blood flow and oxygenation. Therefore, all the choices (A, B, and C) are correct as inhaling carbogen can have multiple beneficial effects on respiration, blood vessels, and blood clot dislodging.

A client asks the nurse what PSA is. The nurse should reply that is stands for:
- A. Prostate-specific antigen, which is used to screen for prostate cancer
- B. Protein serum antigen, which is used to determine protein levels
- C. Pneumococcal strep antigen, which is bacteria that causes pneumonia
- D. Papanicolua-specific antigen, which is used to screen for cervical cancer
Correct Answer: A
Rationale: Rationale for Correct Answer (A): Prostate-specific antigen (PSA) is a protein produced by the prostate gland. It is primarily used to screen for prostate cancer by measuring the levels of PSA in the blood. PSA levels can help detect prostate cancer early. Therefore, choice A is the correct answer as it accurately describes PSA and its primary use.
Summary of Incorrect Choices:
B: Protein serum antigen is not a commonly known term in healthcare. There is no specific antigen called "protein serum antigen" used to determine protein levels.
C: Pneumococcal strep antigen is a bacterial antigen that causes pneumonia, not related to PSA used in prostate cancer screening.
D: Papanicolua-specific antigen is not a recognized term. The Papanicolaou test (Pap smear) is used for cervical cancer screening, not a specific antigen like PSA.
At a public health fair, a nurse discusses the dangers of sun exposure. Prolonged sun exposure has been blamed for which form of cancer?
- A. Malignant melanoma
- B. Basal cell epithelioma
- C. Squamous cell carcinoma
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D, "All of the above." Malignant melanoma, basal cell epithelioma, and squamous cell carcinoma are all types of skin cancer associated with prolonged sun exposure. Melanoma is the most dangerous form, while basal cell and squamous cell carcinomas are more common but less aggressive. Sun exposure can lead to DNA damage in skin cells, increasing the risk of developing these types of cancers. Therefore, all three choices are correct as they are all linked to sun exposure. The other choices are incorrect because each type of skin cancer mentioned can be caused by prolonged sun exposure, so selecting any one of them individually would not fully capture the scope of the risks associated with sun exposure.
The client with rheumatoid arthritis reports GI irritation after taking piroxicam (Feldene). To prevent GI upset, the nurse should provide which instruction?
- A. Space the administration every 4 hours.
- B. Use the drug for a short time only
- C. Take piroxicam with food or oral antacid
- D. Decrease the piroxicam dosage
Correct Answer: C
Rationale: The correct answer is C: Take piroxicam with food or oral antacid. This instruction helps to reduce GI irritation by providing a protective barrier for the stomach lining. Piroxicam is known to cause GI upset due to its effect on prostaglandin synthesis. Taking it with food or an antacid can help minimize this side effect.
Choice A (Space the administration every 4 hours) does not address the issue of GI irritation and is not a recommended strategy for preventing this side effect.
Choice B (Use the drug for a short time only) is not a direct intervention to prevent GI upset and does not provide guidance on how to manage the side effect when taking the medication.
Choice D (Decrease the piroxicam dosage) may not be necessary if the client can manage the side effects with the simple intervention of taking it with food or an antacid.
Which of the ff finding would confirm that a female client has mastitis? Choose all that apply
- A. A crack in the nipple or the areola
- B. Multiple lumps within the breast tissue
- C. Swollen, firm, and hard breasts
- D. Enlargement of the axillary lymph nodes
Correct Answer: C
Rationale: The correct answer is C because mastitis typically presents with swollen, firm, and hard breasts due to inflammation and infection of the breast tissue. This occurs as a result of milk stasis and bacterial infection. Option A is incorrect because a crack in the nipple or areola can be indicative of nipple trauma or infection, not necessarily mastitis. Option B is incorrect because multiple lumps within the breast tissue may suggest fibrocystic changes or breast cancer, but not specifically mastitis. Option D is incorrect because enlargement of the axillary lymph nodes is more commonly seen in breast cancer, not mastitis.
The nurse expects to note an elevated serum glucose level in a client with hyperosmolar hyperglycemic nonketonic syndrome (HHNS). Which other laboratory finding should the nurse anticipate?
- A. Elevated serum acetone level
- B. Serum alkalosis
- C. Serum ketone bodies
- D. Below-normal serum potassium level
Correct Answer: D
Rationale: Step 1: In HHNS, there is severe hyperglycemia leading to osmotic diuresis.
Step 2: Osmotic diuresis causes loss of potassium in urine, leading to hypokalemia.
Step 3: Hypokalemia is a common electrolyte imbalance in HHNS due to excessive urinary loss of potassium.
Step 4: Therefore, the nurse should anticipate a below-normal serum potassium level in a client with HHNS.
Summary:
A: Elevated serum acetone level is seen in diabetic ketoacidosis, not HHNS.
B: Serum alkalosis is not typically associated with HHNS.
C: Serum ketone bodies are elevated in diabetic ketoacidosis, not HHNS.
