1. Do sebaceous glands cause a developing organism to grow arms or wings, skin, or scales?

Correct answer: B

Rationale: The correct answer is B: False. Sebaceous glands are associated with the skin's oil production and have no role in the development of limbs or body coverings. Sebaceous glands primarily produce sebum, an oily substance that lubricates and waterproofs the skin and hair. Choices A, C, and D are incorrect because sebaceous glands do not influence the growth of arms, wings, skin, or scales in a developing organism.

2. What causes cystic fibrosis?

Correct answer: C

Rationale: Cystic fibrosis is a genetic disorder caused by inheriting two copies of a recessive gene, one from each parent. This means that both parents must carry at least one copy of the faulty gene for a child to inherit the condition. Choice A is incorrect because cystic fibrosis is not linked to the sex chromosomes. Choice B is incorrect as cystic fibrosis is not caused by an abnormality in the 21st pair of chromosomes but by a specific gene mutation. Choice D is also incorrect as cystic fibrosis is not related to the Y chromosome, which is specific to males.

3. A nurse is teaching about clomiphene citrate to a client who is experiencing infertility. Which of the following adverse effects should the nurse include?

Correct answer: C

Rationale: The correct answer is C: 'Breast Tenderness.' Clomiphene citrate is known to cause breast tenderness as a common side effect due to its hormonal effects on the body. Tinnitus (choice A), which is a ringing in the ears, is not typically associated with clomiphene citrate. Urinary frequency (choice B) is not a common adverse effect of this medication. Chills (choice D) are also not commonly linked to clomiphene citrate use.

4. A new parent is receiving discharge teaching about car seat safety from a nurse. Which statement by the parent indicates an understanding of the teaching?

Correct answer: A

Rationale: The correct answer is A. Positioning the car seat at a 45-degree angle is crucial to prevent the baby's head from falling forward, which can obstruct the airway. Choice B is incorrect because the recommendation is to keep the car seat rear-facing until the baby reaches the height or weight limit set by the car seat manufacturer, typically beyond 12 months. Choice C is incorrect as the harness should be snugly placed at or below the baby's shoulders, not above. Choice D is incorrect as the retainer clip should be positioned at armpit level to secure the harness straps properly.

5. _________ are problems that stem from the interaction of heredity and environmental factors.

Correct answer: A

Rationale: Multifactorial problems are conditions that result from the interplay of genetic and environmental factors. These conditions, such as diabetes or heart disease, are not solely determined by genetics or environment but are influenced by a combination of both factors. Choice B, cognitive problems, refers to difficulties related to thinking, learning, and memory and are not specifically linked to genetic and environmental interactions. Choices C and D, horizon problems and coronal problems, are nonsensical terms and do not relate to the interaction of heredity and environmental factors.
