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.

• A. A only
• B. B only
• C. A and B
• D. O

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. A 70-year-old woman has difficulty with driving, and she has been frequently getting lost. Her husband said she has also been acting strange and seems to want to sleep a lot. He said the other night she kept saying she was seeing animals such as lions in her room. He says her memory is not too bad, but he is very concerned about her health. Physical examination reveals an alert woman with stable vital signs. Bradykinesia and limb rigidity are noted. These findings are consistent with:

• A. Alzheimer's disease.
• B. Vascular dementia.
• C. Dementia with Lewy bodies.
• D. Frontotemporal dementia.

Correct answer: C

Rationale: The symptoms described in the scenario, such as visual hallucinations, fluctuations in cognition, and parkinsonism (bradykinesia and limb rigidity), are classic features of dementia with Lewy bodies (DLB). DLB is characterized by the presence of Lewy bodies in the brain, which are abnormal protein deposits. Alzheimer's disease (Choice A) typically presents with memory loss as a predominant symptom, which is not a major concern in this case. Vascular dementia (Choice B) is associated with a history of cerebrovascular disease and is not supported by the symptoms described. Frontotemporal dementia (Choice D) usually presents with changes in behavior and personality, rather than the symptoms described in the scenario.

3. Which of the following birthmarks usually fade or regress as the child gets older?

• A. Hemangiomas
• B. Congenital dermal melanocytosis (i.e., Mongolian spots)
• C. Macular stains
• D. Hemangiomas, congenital dermal melanocytosis (i.e., Mongolian spots), and macular stains

Correct answer: D

Rationale: The correct answer is Hemangiomas, congenital dermal melanocytosis (i.e., Mongolian spots), and macular stains. These three types of birthmarks are known to fade or regress as the child gets older. Hemangiomas are vascular birthmarks that often shrink and disappear over time. Congenital dermal melanocytosis, commonly known as Mongolian spots, usually fade by adolescence. Macular stains, also called salmon patches, tend to lighten and fade as a child grows. The other choices are incorrect because they do not typically fade or regress with age.

4. A 9-year-old girl has a diffuse collection of symptoms that are indicative of deficits in endocrine and autonomic nervous system control. She also suffers from persistent fluid and electrolyte imbalances. On which aspect of the nervous system listed below would her health care providers focus their diagnostic efforts?

• A. The thalamus
• B. The pituitary
• C. The hypothalamus
• D. The midbrain

Correct answer: C

Rationale: The correct answer is C: The hypothalamus. The hypothalamus plays a central role in regulating endocrine and autonomic functions, including fluid and electrolyte balance. In this case, the girl's symptoms of deficits in endocrine and autonomic nervous system control, along with fluid and electrolyte imbalances, point towards dysfunction in the hypothalamus. Choices A, B, and D are incorrect because the thalamus is mainly involved in sensory relay, the pituitary gland regulates various hormones but is controlled by the hypothalamus, and the midbrain is responsible for motor control and arousal, not endocrine or autonomic functions.

5. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What key instruction should the nurse provide regarding the use of this medication?

• A. Take the medication at the same time each day to maintain consistent hormone levels.
• B. Medroxyprogesterone should be taken with food to reduce gastrointestinal upset.
• C. Medroxyprogesterone should be discontinued if side effects occur.
• D. Medroxyprogesterone should be taken once a week to maintain effectiveness.

Correct answer: A

Rationale: The correct instruction the nurse should provide regarding the use of medroxyprogesterone acetate (Provera) for endometriosis is to take the medication at the same time each day. This helps to maintain consistent hormone levels and ensures the effectiveness of the treatment. Choice B is incorrect because medroxyprogesterone should be taken without regard to meals. Choice C is incorrect because side effects should be reported to the healthcare provider for evaluation rather than discontinuing the medication without medical advice. Choice D is incorrect as medroxyprogesterone is usually taken daily, not weekly, for the treatment of endometriosis.
