Nursing Elites

1. Patients exhibiting signs of cyanosis will:

• A. show signs of hyperoxia.
• B. have increased O2 saturation.
• C. have blood levels of CO2 higher than O2 levels.
• D. None of the above.

Correct answer: C

Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.

2. When examining an infant, which area should the nurse examine first?

• A. Ear
• B. Nose
• C. Throat
• D. Abdomen

Correct answer: D

Rationale: When examining an infant, the nurse should start by examining the least-distressing areas first before moving on to more invasive areas. The abdomen is typically the least distressing area to examine, so it should be assessed first. Examining the eye, ear, nose, and throat are considered more invasive and should be saved for last. Therefore, the correct choice is to examine the abdomen first to ensure a comfortable and less distressing examination process for the infant. Choices A, B, and C (Ear, Nose, Throat) are more invasive areas and should be examined after the abdomen.

3. Where is the duodenum located in the digestive system?

• A. It is the first part of the small intestine, located immediately after the stomach.
• B. It is the section of the digestive system where the gall bladder delivers bile.
• C. It is the section of the small intestine where the pancreas delivers digestive juices.
• D. None of the above.

Correct answer: D

Rationale: The duodenum is the first part of the small intestine, located immediately after the stomach. It is where the majority of digestion takes place in the gut. The pancreas delivers digestive juices containing amylase and lipase, while the gall bladder delivers bile to aid in the digestion of fats. Choice A incorrectly states that the duodenum is the third section of the small intestine, which is inaccurate. Choice B incorrectly associates the duodenum with the gall bladder, which is not where the duodenum is located. Choice C incorrectly states that the duodenum is where the pancreas delivers digestive juices, which is partly correct but not the main function of the duodenum. Therefore, the correct answer is 'None of the above' as none of the choices accurately describe the location or functions of the duodenum.

4. Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?

• A. One light blue, one red
• B. Two lavenders
• C. One lavender, one grey
• D. One green, one red

Correct answer: D

Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes. Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.

5. The healthcare provider is reviewing theories of illness. The germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions, is a basic belief of which theory of illness?

• A. Holistic
• B. Biomedical
• C. Naturalistic
• D. Magicoreligious

Correct answer: B

Rationale: The correct answer is B: Biomedical. Among the biomedical explanations for disease is the germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions. The naturalistic or holistic perspective holds that the forces of nature must be kept in natural balance. The magicoreligious perspective holds that supernatural forces dominate and cause illness or health. Therefore, options A, C, and D are incorrect as they do not align with the germ theory explanation provided in the question.
