1. When a healthcare professional notices that a patient has type O blood, they realize that anti-_____ antibodies are present in the patient's body.

Correct answer: C

Rationale: Individuals with type O blood have both anti-A and anti-B antibodies in their body. This is because type O blood lacks A or B antigens on the surface of red blood cells, causing the body to produce antibodies against both A and B antigens. Therefore, the correct answer is C. Choice A and B only antibodies are incorrect because type O individuals have both anti-A and anti-B antibodies. Choice D is incorrect as O represents the blood type itself, not the antibodies present in the blood.

2. The healthcare provider is caring for a client with an altered level of consciousness and needs to assess the withdrawal reflex. Which action should the healthcare provider perform?

Correct answer: A

Rationale: The withdrawal reflex is assessed by applying a painful stimulus and observing if the client pulls away. This response indicates a functioning reflex arc. Choices B, C, and D are incorrect as they do not involve testing the withdrawal reflex specifically. Checking for pupil response to light assesses the pupillary reflex, assessing the client's response to verbal commands evaluates their cognitive function, and observing the client's reaction to a cold stimulus tests for a different type of sensory response.

3. A nurse is conducting an assessment on a client who presents with symptoms that are characteristic of amyotrophic lateral sclerosis (ALS). What assessment finding would be expected in this client?

Correct answer: D

Rationale: The correct answer is D: Hyperreflexia. In amyotrophic lateral sclerosis (ALS), hyperreflexia is a common assessment finding due to the degeneration of upper motor neurons. This results in an overactive reflex response to stimuli. Reduced reflexes in all four limbs (choice A) are not typically seen in ALS; instead, hyperreflexia is more common. Decreased cognitive function (choice B) is not a primary characteristic of ALS. Involuntary muscle contractions (choice C) are more indicative of conditions such as dystonia or myoclonus, not ALS.

4. Which of the following statements describes an active cellular membrane exchange process?

Correct answer: A

Rationale: The correct answer is A. In active transport, energy is expended to move substances against their concentration gradient. Sodium moving out of cells and potassium moving into cells is an example of active transport because it requires energy to pump these ions across the cell membrane against their concentration gradients. Choices B, C, and D describe passive processes where substances move along their concentration gradients without the input of energy.

5. A male patient receiving androgen therapy is concerned about side effects. What adverse effect should the nurse monitor for during this therapy?

Correct answer: B

Rationale: The correct answer is B: Increased risk of cardiovascular events. Androgen therapy can lead to an increased risk of cardiovascular events such as heart attack and stroke, especially in older patients. Choice A is incorrect because androgen therapy usually does not significantly increase the risk of liver dysfunction. Choice C is incorrect as androgen therapy does not increase the risk of prostate cancer; in fact, it is sometimes used in the treatment of prostate cancer. Choice D is also incorrect as androgen therapy is more likely to improve bone density and reduce the risk of fractures.
