Nursing Elites

1. A client asks a nurse working in a dental office what type of drug the dentist uses to provide anesthesia during the extraction of the client's wisdom teeth. The dentist uses an anesthetic gas, also known as laughing gas. This agent is:

• A. nitrous oxide.
• B. nitrogen.
• C. nitric oxide.
• D. nitrogen dioxide.

Correct answer: A

Rationale: The correct answer is nitrous oxide. Nitrous oxide is commonly known as laughing gas and is used as an anesthetic gas for procedures like dental extractions. It produces analgesia and mild euphoria without loss of consciousness. Nitrogen is a nonmetallic element found in air, while nitric oxide is a vasodilator produced from L-arginine. Nitrogen dioxide is a poisonous gas found in smog and exhaust fumes and is not used for anesthesia.

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. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

4. What type of diet is appropriate for a client with chronic cirrhosis?

• A. High calorie, low protein
• B. High protein, high calorie
• C. Low fat, low sodium
• D. High calorie, low sodium

Correct answer: A

Rationale: The correct diet for a client with chronic cirrhosis is high calorie, low protein. Cirrhosis can lead to impaired protein metabolism, making it essential to limit protein intake. High-calorie foods help meet the client's energy needs. Choice B (High protein, high calorie) is incorrect because high protein intake can worsen hepatic encephalopathy. Choice C (Low fat, low sodium) is not the most appropriate diet for cirrhosis as the focus should be on calories and protein. Choice D (High calorie, low sodium) does not address the need to restrict protein intake, which is crucial in cirrhosis.

5. A nurse reviews the health history of a client who will be seeing the health care provider to obtain a prescription for a combination oral contraceptive (estrogen and progestin). Which finding in the health history would cause the nurse to determine that the use of a combination oral contraceptive is contraindicated?

• A. The client has type 2 diabetes mellitus.
• B. The client is being treated for hypertension.
• C. The client has been treated for breast cancer.
• D. The client has hyperlipidemia.

Correct answer: C

Rationale: The correct answer is that the client has been treated for breast cancer. Combination oral contraceptives containing estrogen and progestin are contraindicated for women with a history of certain conditions, such as thrombophlebitis, thromboembolic disorders, cerebrovascular disease, coronary artery disease, myocardial infarction, known or suspected breast cancer, known or suspected estrogen-dependent neoplasm, benign or malignant liver tumors, and undiagnosed abnormal genital bleeding. Although having type 2 diabetes mellitus, being treated for hypertension, or having hyperlipidemia are risk factors that require caution when using combination oral contraceptives, they are not absolute contraindications like a history of breast cancer.
