The nurse explains to a client that she will administer his first insulin dose in his abdomen. How does absorption at the abdominal site compare to absorption at other sites?

Correct Answer: C

Rationale: Rationale: 1. Abdominal injection sites have a higher blood supply, leading to faster absorption. 2. Insulin absorption is faster in areas with more blood vessels. 3. Rapid absorption at the abdomen results in quicker onset of action. 4. Other sites may have slower absorption due to less blood flow. Summary: A: Incorrect. Absorption is faster at abdominal sites due to increased blood flow. B: Incorrect. Absorption varies based on injection site blood supply. C: Correct. Abdominal injection sites have rapid insulin absorption. D: Incorrect. Insulin absorption is consistent based on blood flow at injection sites.

Correct Answer: C

Rationale: The correct answer is C: Trunk. The thoracic cord supplies nerves to the trunk region of the body. The thoracic spinal nerves innervate the chest, abdomen, and back. They control sensation and movement in these areas. The head (A) is mainly supplied by cranial nerves, the pelvis (B) is innervated by lumbar and sacral nerves, and the coccyx (D) is supplied by the sacral nerves. Therefore, the correct answer is C as it aligns with the anatomical distribution of the thoracic spinal nerves.

Correct Answer: B

Rationale: The correct answer is B: Pupil responses. During an ophthalmic assessment, observing pupil responses is crucial as it provides information on the function of the cranial nerves and potential neurological issues. Pupil size, shape, symmetry, and reaction to light are key indicators of eye health. A: Level of central vision - While important, assessing the level of central vision is typically done by the ophthalmologist and not within the scope of the nurse's role in a routine assessment. C: External eye appearance - Although external eye appearance can give some clues about eye health, it is not as direct and crucial as observing pupil responses. D: Eye movements - While eye movements can provide information on ocular motor function, it is not as critical as assessing pupil responses in an ophthalmic assessment.

Correct Answer: D

Rationale: The correct answer is D: Maturates T cells. The thymus gland is crucial for the maturation of T cells, a type of white blood cell that plays a central role in the adaptive immune response. T cells mature in the thymus through a process of selection and education, where they learn to distinguish self from non-self antigens. This process is essential for the development of a functional immune system. Choices A, B, and C are incorrect because the thymus gland does not play a role in the maturation of B cells, platelets, or red blood cells, respectively.

Correct Answer: C

Rationale: Rationale: Parkinson's disease is characterized by dopamine deficiency in the brain, leading to motor symptoms like bradykinesia, rigidity, and tremors. Dopamine is crucial for controlling movement. Acetylcholine (A) is not directly related to Parkinson's symptoms. Serotonin (B) is involved in mood regulation, not movement control. Phenylalanine (D) is an amino acid and not directly related to Parkinson's pathology. Therefore, the correct answer is C.

Correct Answer: A

Rationale: The correct answer is A: Denial. The client's refusal to accept the diagnosis of diabetes mellitus, stating that no one in their family has had it, indicates denial as a coping mechanism. Denial is a defense mechanism where individuals refuse to acknowledge unpleasant realities. In this case, the client is rejecting the diagnosis to avoid facing the reality of having a chronic condition. The other choices (B: Anger, C: Withdrawal, D: Resolution) do not fit the client's response in this scenario. Anger involves expressing frustration or hostility, withdrawal is avoiding the situation, and resolution is accepting and dealing with the issue.

Correct Answer: D

Rationale: The correct answer is D: “Your heart is not an efficient pump.” This response is the best choice as it accurately describes heart failure, which is a condition where the heart is unable to pump blood effectively. This leads to symptoms such as fatigue, shortness of breath, and fluid retention. Explanation: 1. Choice A is incorrect because heart failure does not mean the heart stops; it means the heart is not functioning properly. 2. Choice B is incorrect because heart failure does not necessarily mean there is dead muscle tissue in the heart. 3. Choice C is incorrect because heart failure is not about pumping too much blood; it is about the heart's inability to pump blood efficiently, leading to circulation problems and other symptoms.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Metabolic acidosis is characterized by low pH and low plasma bicarbonate. 2. In this condition, there is an excess of acids or a loss of bicarbonate. 3. The kidneys are unable to adequately excrete acids or retain bicarbonate. 4. This leads to a decrease in bicarbonate levels and a decrease in pH. 5. Respiratory acidosis (A) is characterized by low pH and high CO2 levels. 6. Respiratory alkalosis (C) is characterized by high pH and low CO2 levels. 7. Metabolic alkalosis (D) is characterized by high pH and high bicarbonate levels. Summary: - Choice A is incorrect as it describes a condition with high CO2 levels. - Choice C is incorrect as it describes a condition with high pH. - Choice D is incorrect as it describes a condition with high bicarbonate levels. - Choice B is correct as it accurately describes the characteristics of a condition with low pH

Correct Answer: B

Rationale: The correct answer is B because a fixed nodular mass with dimpling of the overlying skin is highly indicative of breast cancer. This finding suggests an invasive tumor pulling on the skin, causing dimpling. Other choices are incorrect because slight breast asymmetry (A) is common, bloody nipple discharge (C) can be benign or due to other conditions, and multiple freely movable masses (D) are more indicative of benign breast conditions like fibrocystic changes.
