1. What outcome has been shown to be a benefit of breastfeeding that directly impacts the mother?

• A. conserving calcium stores
• B. contracting the uterus
• C. protecting against future hypertension
• D. speeding the resumption of ovulation

Correct answer: B

Rationale: The correct answer is B, contracting the uterus. Breastfeeding helps contract the uterus after childbirth, reducing postpartum bleeding and helping the uterus return to its pre-pregnancy size more quickly. Choices A, C, and D are incorrect because conserving calcium stores, protecting against future hypertension, and speeding the resumption of ovulation are not direct benefits of breastfeeding to the mother.

2. A condition that is conducive to the development of dental caries is said to be _____.

• A. periodontal
• B. cariogenic
• C. gingival
• D. bacteriophilic

Correct answer: B

Rationale: A condition that is conducive to the development of dental caries is described as cariogenic. Cariogenic refers to foods or conditions that promote the development of dental caries by providing an environment for bacteria to thrive and produce acids that erode tooth enamel. Choice A, periodontal, is incorrect as it relates to the supporting structures of the teeth rather than the development of dental caries. Choice C, gingival, is also incorrect as it pertains to the gums rather than the causation of dental caries. Choice D, bacteriophilic, is not the term commonly used to describe conditions that lead to dental caries, making it an incorrect choice.

3. High intakes of which of the following interfere with copper absorption and can lead to a deficiency?

• A. chromium
• B. sodium
• C. zinc
• D. manganese

Correct answer: C

Rationale: The correct answer is C, zinc. High intakes of zinc can interfere with copper absorption, potentially leading to copper deficiency. Copper is essential for various bodily functions, including iron metabolism. Choice A, chromium, is incorrect because chromium does not interfere with copper absorption. Choice B, sodium, and Choice D, manganese, are also incorrect as they do not interfere with copper absorption.

4. To ensure client safety before starting blood transfusions, the following are needed before the procedure can be done EXCEPT:

• A. take baseline vital signs
• B. warm the blood to room temperature for 30 minutes before administering the transfusion
• C. have two nurses verify client identification, blood type, unit number, and expiration date of blood
• D. get consent signed for blood transfusion

Correct answer: D

Rationale: To ensure client safety before starting blood transfusions, taking baseline vital signs, warming the blood to room temperature, and having two nurses verify client identification, blood type, unit number, and expiration date of blood are crucial steps. Consent for blood transfusion is required but is typically obtained before the procedure. The focus before the procedure should be on confirming the right client, blood product, and ensuring the blood is prepared correctly to minimize risks of transfusion reactions.

5. The purpose of chest percussion and vibration is to loosen secretions in the lungs. The difference between the procedures is:

• A. Percussion uses only one hand, while vibration uses both hands
• B. Percussion delivers cushioned blows to the chest with cupped palms, while vibration gently shakes secretions loose
• C. In both percussion and vibration, the hands are not on top of each other, and hand action is not in tune with the client's breath
• D. Percussion slaps the chest to loosen secretions, while vibration shakes the secretions along with the inhalation

Correct answer: D

Rationale: Chest percussion involves the use of rhythmic tapping to dislodge mucus from the lungs, facilitating its movement toward the larger airways where it can be expelled. This technique is particularly important in conditions where mucus retention is a significant risk factor for infection. The key difference between chest percussion and vibration is that percussion involves slapping the chest to loosen secretions, while vibration involves shaking the secretions along with the inhalation, aiding in moving the loosened secretions upwards for easier removal. Choices A, B, and C do not accurately describe the main difference between chest percussion and vibration, making them incorrect.
