Nursing Elites

1. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

• A. PaO2 90 mm Hg
• B. Bicarbonate 15 mEq/L
• C. CO2 47 mm Hg
• D. pH 7.34

Correct answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.

2. When giving an intramuscular injection to an infant, which of the following sites is preferred?

• A. Ventrogluteal region
• B. Deltoid
• C. Vastus lateralis
• D. Dorsogluteal region

Correct answer: C

Rationale: The correct answer is the Vastus lateralis when giving an intramuscular injection to an infant. The Vastus lateralis muscle, located in the thigh, is the preferred site for infants as it has a larger muscle mass and is well-developed, making it suitable for injections. The Ventrogluteal region and Dorsogluteal region are not recommended for infants due to their smaller muscle mass and potential risk of damaging nearby structures. The Deltoid muscle is typically used for older children and adults, not infants.

3. Why must the nurse be careful not to cut through or disrupt any tears, holes, bloodstains, or dirt present on the clothing of a client who has experienced trauma?

• A. The clothing may be potential evidence with legal implications.
• B. Such care facilitates the preservation of potential evidence.
• C. The clothing of a trauma victim can be used for further investigation.
• D. Such care maintains the integrity of the clothing for forensic analysis.

Correct answer: C

Rationale: In cases of trauma, the clothing of a client can hold crucial evidence that may have legal implications. It is essential for the nurse to avoid cutting through or disrupting any tears, holes, bloodstains, or dirt present on the clothing to preserve this potential evidence. The correct answer highlights the legal importance of preserving the clothing for potential legal implications. Choice B is related but does not emphasize the legal aspect explicitly. Choice C is vague in mentioning further investigation without specifying the legal significance. Choice D focuses more on forensic analysis rather than the legal implications of preserving the clothing.

4. Which symptom is the client who self-administered an overdose of acetaminophen most likely to exhibit?

• A. Pink frothy sputum
• B. Seizure activity
• C. Jaundiced conjunctiva
• D. Diaphoresis and fever

Correct answer: C

Rationale: When a client self-administers an overdose of acetaminophen, the liver is primarily affected. Jaundiced conjunctiva, which is yellowing of the eyes, is a common symptom of liver damage. Pink frothy sputum is typically associated with conditions like pulmonary edema, not acetaminophen overdose. Seizure activity is not a common symptom of acetaminophen overdose but can be seen in other toxicities. Diaphoresis and fever are more generalized symptoms and not specific to acetaminophen overdose.

5. Which of the following organs of the digestive system has a primary function of absorption?

• A. stomach
• B. pancreas
• C. small intestine
• D. gallbladder

Correct answer: C

Rationale: The small intestine is the correct answer. It is the primary organ responsible for absorption in the digestive system. The stomach's primary function is to break down food through mechanical and chemical digestion. The pancreas produces digestive enzymes to aid in the breakdown of food. The gallbladder stores bile produced by the liver, which helps in the digestion of fats. However, neither the stomach, pancreas, nor gallbladder play the primary role of absorption in the digestive process, making them incorrect choices.
