Adult Health Exam 1
1. A grand multiparous client had a precipitous delivery in the emergency room 6 hours ago. The client was given oxytocin intramuscularly after birth. The nurse examines the client and observes the pad under her buttocks is full of blood. Which action should the nurse take first?
- A. Place a new pad and weigh the pad removed to determine blood loss.
- B. Massage the fundus and express clots.
- C. Start an IV and begin an oxytocin infusion.
- D. Clean the perineal area and encourage her to breastfeed.
Correct answer: B
Rationale: Massaging the fundus and expressing clots helps contract the uterus and reduce postpartum hemorrhage.
2. A client with asthma is prescribed an albuterol inhaler. Which instruction should the nurse provide?
- A. Use the inhaler only during an asthma attack
- B. Rinse your mouth after using the inhaler
- C. Shake the inhaler before each use
- D. Exhale fully before inhaling the medication
Correct answer: C
Rationale: The correct instruction for the nurse to provide is to shake the inhaler before each use. Shaking the inhaler ensures proper mixing of the medication before administration, which is crucial for its effectiveness. Choice A is incorrect because albuterol inhalers are often used as a preventive measure, not just during asthma attacks. Choice B is a good practice to prevent oral fungal infections associated with inhaled corticosteroids, not typically with albuterol. Choice D is important for proper inhaler technique, but the primary step before inhaling is shaking the inhaler to ensure the medication is well mixed.
3. What is the primary function of neutrophils?
- A. Heparin secretion
- B. Transport oxygen
- C. Phagocytotic action
- D. Antibody formation
Correct answer: C
Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
4. What are the final factors that contribute to blood pressure? (Select all that apply)
- A. Heart rate
- B. Stroke volume
- C. Peripheral resistance
- D. Neuroendocrine hormones
Correct answer: D
Rationale: Neuroendocrine hormones play a crucial role in regulating blood pressure by influencing factors like fluid balance, blood volume, and vessel constriction. While heart rate, stroke volume, and peripheral resistance are important factors affecting blood pressure, the final parameters that directly produce blood pressure are influenced by neuroendocrine hormones. Therefore, choice D is the correct answer. Choices A, B, and C are involved in the regulation of blood pressure but are not the final parameters that directly produce it.
5. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?
- A. Filtration
- B. Diffusion
- C. Osmosis
- D. Active transport
Correct answer: C
Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.
