is self propulsion

1. _________ is self-propulsion.

A. Mitosis
B. Meiosis
C. Motility
D. Mutation

Correct answer: C

Rationale: The correct answer is 'Motility.' Motility refers to the ability of cells or organisms to move by themselves, often through the use of specialized structures like flagella or cilia. Mitosis (Choice A) and Meiosis (Choice B) are processes related to cell division and genetic recombination, respectively, not self-propulsion. Mutation (Choice D) refers to changes in the DNA sequence and is not related to self-propulsion.

2. A client experiencing preterm labor is being taught about terbutaline by a nurse. Which statement by the client indicates an understanding of the teaching?

A. “The medication could cause me to experience heart palpitations.”
B. “This medication could cause me to experience blurred vision.”
C. “This medication could cause me to experience ringing in my ears.”
D. “This medication could cause me to experience frequent urination.”

Correct answer: A

Rationale: The correct answer is A. Terbutaline is a beta-adrenergic agonist used to stop preterm labor. One of its common side effects is heart palpitations due to its action on beta receptors in the heart. Choices B and C are incorrect because blurred vision and ringing in the ears are not common side effects of terbutaline. Choice D is irrelevant to the side effects of terbutaline.

3. On the first postpartum day, the nurse examines the breasts of a new mother. Which condition is the nurse most likely to find?

A. Firm, larger, and very tender to the touch
B. Slightly firm with an immediate let-down response
C. Soft with no change from before delivery
D. Filling and secreting colostrum

Correct answer: D

Rationale: On the first postpartum day, the nurse is most likely to find the breasts filling and secreting colostrum. Colostrum secretion is common as the body prepares for breastfeeding in the initial days after delivery. Choice A is incorrect as breasts are not typically very tender immediately postpartum. Choice B is incorrect as an immediate let-down response is more related to lactation rather than the first postpartum day. Choice C is incorrect as the breasts typically undergo changes, such as filling with colostrum, after delivery.

4. A healthcare provider is assessing a preterm newborn who is at 32 weeks of gestation. Which of the following finding should the healthcare provider expect?

A. Minimal arm recoil
B. Popliteal angle of less than 90°
C. Creases over the entire sole
D. Sparse lanugo

Correct answer: A

Rationale: When assessing a preterm newborn at 32 weeks of gestation, healthcare providers should expect minimal arm recoil. This finding is common in preterm infants due to lower muscle tone. Choice B, a popliteal angle of less than 90°, is incorrect for this age group. Creases over the entire sole (Choice C) typically develop at term age, not at 32 weeks of gestation. Sparse lanugo (Choice D) is a normal finding in preterm infants but is not specific to those at 32 weeks of gestation.

5. Most victims of _____ die of respiratory infections in their 20s.

A. Tay-Sachs disease
B. cystic fibrosis
C. Turner syndrome
D. Klinefelter syndrome

Correct answer: B

Rationale: Individuals with cystic fibrosis have a genetic disorder that causes mucus to be thick and sticky, leading to blockages in the lungs and digestive system. This mucus buildup makes them more susceptible to severe respiratory infections, which can ultimately result in premature death in their 20s. Tay-Sachs disease (Choice A) is a genetic disorder that affects the nervous system, not typically causing respiratory infections. Turner syndrome (Choice C) and Klinefelter syndrome (Choice D) are chromosomal disorders that do not directly lead to the respiratory issues observed in cystic fibrosis.
