While measuring a patient's blood pressure, which factor influences a patient's blood pressure?
- A. Pulse rate
- B. Pulse pressure
- C. Vascular output
- D. Peripheral vascular resistance
Correct Answer: D
Rationale: When measuring a patient's blood pressure, it is important to consider various factors that influence blood pressure. Peripheral vascular resistance plays a crucial role in regulating blood pressure. The level of blood pressure is affected by factors such as cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, and elasticity of the vessel walls. Pulse rate (Choice A) refers to the number of heartbeats per minute and is not a primary factor influencing blood pressure. Pulse pressure (Choice B) is the difference between systolic and diastolic blood pressure and does not directly impact blood pressure regulation. Vascular output (Choice C) is not a recognized term in blood pressure regulation and is not a primary factor affecting blood pressure.

The nurse is assessing an 8-year-old child whose growth rate measures below the third percentile for
a child his age. He appears significantly younger than his stated age and is chubby with infantile
facial features. Which condition does this child likely have?
- A. Acromegaly
- B. Marfan syndrome
- C. Hypopituitary dwarfism
- D. Achondroplastic dwarfism
Correct Answer: C
Rationale: Hypopituitary dwarfism is caused by a deficiency in growth hormone in childhood and results in a
retardation of growth below the third percentile, delayed puberty, and other problems. The child's
appearance fits this description. Achondroplastic dwarfism is a genetic disorder resulting in
characteristic deformities; Marfan syndrome is an inherited connective tissue disorder characterized
by a tall, thin stature and other features. Acromegaly is the result of excessive secretion of growth
hormone in adulthood which causes overgrowth of bone in the face, head, hands, and feet.
When auscultating the blood pressure of a 25-year-old patient, the nurse notices that the phase I Korotkoff sounds begin at 200 mm Hg. At 100 mm Hg, the Korotkoff sounds muffle. At 92 mm Hg, the Korotkoff sounds disappear. How should the nurse record this patient's blood pressure?
- A. 200/92
- B. 200/100
- C. 100/200/92
- D. 200/100/92
Correct Answer: A
Rationale: When auscultating blood pressure, it is crucial to note the points at which Korotkoff sounds change. In adults, the last audible sound indicates the diastolic pressure. In this case, the Korotkoff sounds muffle at 100 mm Hg and disappear at 92 mm Hg. Therefore, the blood pressure should be recorded as systolic/diastolic, which is 200/92. Choices B, C, and D are incorrect because they do not reflect the correct points where the Korotkoff sounds change during blood pressure measurement.
Patients who cannot move in their bed on their own should be turned at least ________________.
- A. once a day
- B. twice a day
- C. every 2 hours
- D. every 4 hours
Correct Answer: C
Rationale: Patients who are unable to move in bed are at high risk of developing pressure ulcers and skin breakdown due to prolonged pressure on specific body areas. Turning these patients at least every 2 hours is crucial to relieve pressure, improve circulation, and prevent skin damage. More frequent turning may be necessary for patients with specific needs, such as those who are incontinent of urine and require additional care. Turning patients less frequently, such as once a day, twice a day, or every 4 hours, increases the risk of developing pressure ulcers and other complications. Therefore, the correct answer is to turn patients who cannot move in their bed on their own every 2 hours.
In a patient with acromegaly, which assessment finding will the nurse expect to find?
- A. Sternal deformity and hyperextensible joints
- B. Growth retardation and a delayed onset of puberty
- C. Overgrowth of bone in the face, head, hands, and feet
- D. Increased height and weight and delayed sexual development
Correct Answer: C
Rationale: Acromegaly is a condition characterized by excessive secretion of growth hormone in adulthood after normal body growth completion. This hormonal excess leads to overgrowth of bones in the face, head, hands, and feet; however, there is no significant change in height. Stating sternal deformity and hyperextensible joints is incorrect as they are characteristic findings of Marfan syndrome. Growth retardation and delayed onset of puberty are not typical of acromegaly but are seen in hypopituitary dwarfism. Increased height, weight, and delayed sexual development are features of gigantism, not acromegaly. Therefore, the correct assessment finding in a patient with acromegaly would be overgrowth of bone in the face, head, hands, and feet.
A parent calls the pediatric clinic and is frantic about the bottle of cleaning fluid her child drank for 20 minutes. Which of the following is the most important instruction the nurse can give the parent?
- A. This too shall pass.
- B. Take the child immediately to the ER
- C. Contact the Poison Control Center quickly
- D. Give the child syrup of ipecac
Correct Answer: C
Rationale: In situations where a child has ingested a potentially harmful substance, contacting the Poison Control Center quickly is crucial. The Poison Control Center can provide specific guidance tailored to the child's situation, which can include whether immediate medical attention is necessary or if any actions need to be taken at home. Option A, 'This too shall pass,' is not appropriate as it dismisses the seriousness of the situation. Option B, 'Take the child immediately to the ER,' may not always be the best course of action without guidance from experts. Option D, 'Give the child syrup of ipecac,' is outdated advice and not recommended as a first response to poisoning incidents.
