1. When a healthcare professional is reviewing lab results and notices that the erythrocytes contain an abnormally low concentration of hemoglobin, the healthcare professional calls these erythrocytes:

• A. Hyperchromic
• B. Hypochromic
• C. Macrocytic
• D. Microcytic

Correct answer: B

Rationale: Erythrocytes with an abnormally low concentration of hemoglobin are called hypochromic. Hyperchromic refers to erythrocytes with an abnormally high concentration of hemoglobin. Macrocytic indicates larger than normal red blood cells, while microcytic refers to smaller than normal red blood cells. Therefore, in this scenario, the correct term is hypochromic.

2. Which of the following is a cause of edema?

• A. Decreased plasma proteins
• B. Hypotension
• C. Dehydration
• D. Polyuria

Correct answer: A

Rationale: The correct answer is A: Decreased plasma proteins. Edema can be caused by decreased plasma proteins, which reduce the osmotic pressure that keeps fluid in the blood vessels. Hypotension (choice B) is low blood pressure and is not a direct cause of edema. Dehydration (choice C) involves a lack of body fluid, but it is not a direct cause of edema. Polyuria (choice D) is excessive urination and not a direct cause of edema.

3. The nurse is caring for a client with an astrocytoma. The client asks, 'What do astrocytes do in the brain?' What is the nurse's best response?

• A. Astrocytes help to nourish and support neurons in the brain.
• B. Astrocytes are a type of neuron that transmit electrical signals.
• C. Astrocytes are involved in immune responses in the brain.
• D. Astrocytes help regulate blood flow in the brain.

Correct answer: A

Rationale: Astrocytes play a crucial role in supporting and nourishing neurons by providing metabolic support, maintaining the blood-brain barrier, and regulating the chemical environment of the brain. While astrocytes are essential for brain function, they are not neurons and do not transmit electrical signals (Choice B). Astrocytes are not primarily involved in immune responses in the brain (Choice C) or in regulating blood flow in the brain (Choice D), although they indirectly influence blood flow through their support functions.

4. A 34-year-old woman has presented to the clinic for the first time, and the nurse learns that she has been taking Depo Provera for the past 13 years. This aspect of the woman's medical history should prompt what assessment?

• A. Cardiac stress testing
• B. Renal ultrasound
• C. Bone density testing
• D. Evaluation of triglyceride levels

Correct answer: C

Rationale: The correct answer is bone density testing (Choice C). Long-term use of Depo Provera, a hormonal contraceptive, is associated with decreased bone mineral density. Assessing bone density is crucial to monitor for potential osteoporosis. Cardiac stress testing (Choice A) is not indicated based on the medication history provided. Renal ultrasound (Choice B) and evaluation of triglyceride levels (Choice D) are not directly related to the use of Depo Provera.

5. A group of nursing students and their professor are engaged in a service learning project and will be caring for patients in Haiti. What medication should be administered to prevent the development of malaria?

• A. Metronidazole (Flagyl)
• B. Oprelvekin (Neumega)
• C. Chloroquine phosphate (Aralen)
• D. Chloroprocaine hydrochloride (Nesacaine)

Correct answer: C

Rationale: The correct answer is Chloroquine phosphate (Aralen). Chloroquine is a medication used to prevent and treat malaria. It works by killing the malaria parasite in the red blood cells. Metronidazole (Flagyl) is an antibiotic used to treat various bacterial and parasitic infections, not malaria. Oprelvekin (Neumega) is a medication used to stimulate platelet production. Chloroprocaine hydrochloride (Nesacaine) is a local anesthetic used for epidural anesthesia. Therefore, Chloroquine phosphate is the appropriate medication for preventing malaria in this scenario.
