Which of the following components is associated with hypertonic dehydration?
- A. Plasma sodium levels above 150 mEq/L
- B. Fluid moves from extracellular space to intracellular space
- C. Water loss is greater than electrolyte loss
- D. Physical signs and symptoms are grossly apparent
Correct Answer: C
Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.

An infant is brought to the clinic by his mother, who has noticed that he holds his head in an unusual position and always faces to one side. Which of the following is the most likely explanation?
- A. Torticollis, with shortening of the sternocleidomastoid muscle
- B. Craniosynostosis, with premature closure of the cranial sutures
- C. Plagiocephaly, with flattening of one side of the head
- D. Hydrocephalus, with increased head size
Correct Answer: A
Rationale: The correct answer is torticollis, characterized by the shortening of the sternocleidomastoid muscle, limiting the range of motion of the neck and causing the chin to point to the opposing side. Craniosynostosis is the premature closure of cranial sutures, leading to an abnormal head shape but not necessarily affecting head position. Plagiocephaly is flattening of one side of the head due to external forces or positioning, not muscle shortening. Hydrocephalus presents with an increased head size due to the accumulation of cerebrospinal fluid, not with a fixed head position.
A 32-year-old pregnant woman comes to the clinic for her prenatal visit. The nurse gathers data about her obstetric history, which includes 3-year-old twins at home and a miscarriage 10 years ago at 12 weeks gestation. How would the nurse accurately document this information?
- A. G4 T1 P0 A1 L2
- B. G3 T1 P0 A1 L2
- C. G3 T0 P1 A1 L2
- D. G4 T0 P1 A1 L2
Correct Answer: D
Rationale: The correct answer is G4 T1 P0 A1 L2. This documentation accurately represents the woman's obstetric history.
G4: She is currently pregnant (1), has twins (1), and had a miscarriage (1), totaling four pregnancies.
T1: She has had one pregnancy that resulted in the birth of her twins at term.
P0: She has not had any preterm births.
A1: She had one miscarriage at 12 weeks gestation.
L2: She has two living children (the twins). Therefore, the correct documentation reflects all aspects of her obstetric history as provided.
A patient in the cardiac unit is concerned about the risk factors associated with atherosclerosis. Which of the following are hereditary risk factors for developing atherosclerosis?
- A. Family history of heart disease
- B. Overweight
- C. Smoking
- D. Age
Correct Answer: A
Rationale: A family history of heart disease is an inherited risk factor for developing atherosclerosis. This factor is not modifiable through lifestyle changes. Studies have shown that having a first-degree relative with heart disease significantly increases the individual's risk of developing atherosclerosis. Overweight, smoking, and age are not hereditary risk factors for atherosclerosis. Overweight and smoking are lifestyle-related risk factors, while age is a non-modifiable risk factor that increases with time but is not directly inherited.
A nonimmunized child appears at the clinic with a visible rash. Which of the following observations indicates the child may have rubeola (measles)?
- A. Small blue-white spots are visible on the oral mucosa.
- B. The rash begins on the trunk and spreads outward.
- C. There is low-grade fever.
- D. The lesions have a "teardrop-on-a-rose-petal"? appearance.
Correct Answer: A
Rationale: The presence of small blue-white spots on the oral mucosa, known as Koplik's spots, is characteristic of measles (rubeola) infection. These spots typically appear on the buccal mucosa opposite the second molars, 1-2 days before the rash onset, and last until 2 days after the rash appears. While Koplik's spots are pathognomonic for measles, their absence does not rule out the diagnosis. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because the rash pattern, presence of low-grade fever, and characteristic appearance of lesions are not specific indicators of measles infection.
Which of the following is an example of intragroup conflict?
- A. A nurse writes a grant for a non-profit organization to raise money for advertising
- B. Members of a multidisciplinary team cannot agree on the best course of action for a client
- C. A client does not receive his medication on time because the nurse was on break
- D. A nurse feels frustrated that her employer does not provide on-site child care
Correct Answer: B
Rationale: Intragroup conflict refers to disagreements within a group. The correct answer, 'Members of a multidisciplinary team cannot agree on the best course of action for a client,' exemplifies this type of conflict well. In this scenario, professionals within the same team are unable to reach a consensus on how to proceed with client care. Choices A, C, and D do not reflect intragroup conflict. Writing a grant for a non-profit organization, a client not receiving medication due to a nurse's break, and a nurse feeling frustrated about the lack of on-site child care do not involve conflicts within a group of professionals.
