Correct Answer: B

Rationale: The priority action for the nurse is to contact the physician immediately due to the client's abnormal vital signs. A blood pressure of 90/50, pulse of 132, and respirations of 30 indicate instability and require prompt medical attention. Continuing to monitor vital signs, as in choice A, may lead to a delay in necessary interventions. Asking the client how they feel, as in choice C, provides subjective data and does not address the urgent need for medical intervention. Involving the LPN, as in choice D, is not appropriate in this critical situation where the client's condition is unstable and requires immediate physician assessment and intervention.

Correct Answer: B

Rationale: The correct answer is "I often use a laxative for constipation." Frequent use of laxatives can lead to diarrhea and electrolyte loss, indicating a possible fluid and electrolyte imbalance. Statements A, C, and D are not directly related to fluid and electrolyte imbalance. Statement A about dry skin may suggest dehydration, but it is less specific to electrolyte imbalance than the frequent use of laxatives. Statement C about drinking a lot of iced tea could potentially relate to fluid intake, but it doesn't directly indicate an imbalance. Statement D about dribbling urine is more indicative of a potential urinary issue rather than a fluid and electrolyte imbalance.

Correct Answer: A

Rationale: When providing care to a client with a cough, it is crucial to wear a mask to protect oneself from inhaling respiratory droplets containing infectious agents. The primary mode of transmission for coughs is through airborne droplets, making a mask the most appropriate choice to prevent the spread of respiratory infections. Gloves and gowns are more relevant when there is a risk of contact with bodily fluids, which is not the main concern with a cough. Shoe covers are not necessary in this scenario as the transmission of respiratory infections is not linked to footwear. Therefore, wearing a mask is the best choice to prevent airborne transmission and ensure the safety of the healthcare provider.

Correct Answer: A

Rationale: The correct answer is, "The amount of alcohol that is safe during pregnancy is unknown."? This response is appropriate because there is no known safe amount of alcohol consumption during pregnancy. Consuming any amount of alcohol during pregnancy can pose risks to the developing fetus, leading to conditions like fetal alcohol syndrome, which is a combination of mental and physical abnormalities in infants. Choices B, C, and D are incorrect. Choice B suggests that consuming one or two drinks a day is safe during pregnancy, which is not supported by current medical guidelines. Choice C incorrectly states that only drinking three or more drinks on any given occasion is harmful, when in reality, any amount of alcohol can be harmful to the fetus. Choice D is inappropriate as it suggests that having a drink to relax and sleep is acceptable during pregnancy, which is not the case.

Correct Answer: B

Rationale: The correct answer is 'Mania.' A client with a serum sodium level of 170 meq/L has hypernatremia, which can lead to manic behavior. Hypernatremia is associated with irritability, restlessness, confusion, and in severe cases, manic symptoms. Choices A, C, and D (Anger, Depression, Psychosis) are not typically associated with hypernatremia and are, therefore, incorrect in this context.
