Question 1 of 5
Nurses should understand the chain of infection because it refers to:
Correct Answer: B
Rationale: The chain of infection refers to the sequence required for the transmission of disease, involving steps like the pathogen's presence, movement from a reservoir, and entry into a susceptible host. Understanding this sequence helps healthcare professionals, including nurses, in implementing effective infection control measures.
Choices A, C, and D are incorrect because they do not accurately describe the concept of the chain of infection.
Choice A is too broad and does not specifically address the sequential nature of disease transmission.
Choice C focuses on bacterial clustering rather than the transmission process.
Choice D mentions virulence patterns, which are not the primary focus of the chain of infection concept.
Question 2 of 5
The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?
Correct Answer: B
Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (
Choice
A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (
Choice
C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (
Choice
D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.
Question 3 of 5
What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36mmHg, and HCO3 24 mEq/L?
Correct Answer: B
Rationale: The correct answer is 'homeostasis.' These ABG values fall within normal ranges, indicating a state of balance in the body's acid-base levels.
Choices A, C, and D are incorrect as the ABG values provided do not point towards metabolic alkalosis, respiratory acidosis, or respiratory alkalosis. Instead, the values reflect a state of equilibrium where pH, PO2, PCO2, and HCO3 levels are within the normal range.
Question 4 of 5
A nurse is caring for a client with an elevated cortisol level. The nurse can expect the client to exhibit symptoms of:
Correct Answer: C
Rationale: Elevated cortisol levels can lead to sodium and fluid retention and potassium deficit, resulting in urinary deficit. This imbalance in electrolytes and fluid can cause a decrease in urinary output.
Choices B, hyperpituitarism, and D, hyperthyroidism, are incorrect as they do not directly relate to the symptoms expected with elevated cortisol levels. Option A, urinary excess, is also incorrect as high cortisol levels typically lead to fluid retention and urinary deficit, not excess.
Question 5 of 5
Which of the following is likely to increase the risk of sexually transmitted disease?
Correct Answer: D
Rationale: All of the above factors are likely to increase the risk of sexually transmitted diseases (STDs). Alcohol use can impair judgment, leading to risky sexual behavior. Certain types of sexual practices, especially unprotected sex or multiple partners, increase the likelihood of contracting STDs. While oral contraception use does not directly increase the risk of STDs, it does not protect against them either.
Therefore, all the choices (alcohol use, certain types of sexual practices, and oral contraception use) can contribute to an increased risk of contracting STDs.
