Nursing Elites

1. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

2. When inspecting the ears for cerumen impaction, the nurse checks for which finding?

• A. Redness and swelling of the tympanic membrane
• B. An external auditory canal that is longer than normal
• C. The presence of edema in the external auditory canal
• D. A yellowish or brownish waxy material in the external auditory canal

Correct answer: D

Rationale: When inspecting the ears for cerumen impaction, the nurse should look for a yellowish or brownish waxy material in the external auditory canal. Cerumen, also known as ear wax, is a secretion that can become impacted due to various reasons. It is produced by the vestigial apocrine sweat glands in the external ear canal. Cerumen may partially obscure the eardrum or totally occlude the ear canal. The other options, redness and swelling of the tympanic membrane, an external auditory canal that is longer than normal, and the presence of edema in the external auditory canal, are not indicative findings of cerumen impaction.

3. When testing the function of the oculomotor, trochlear, and abducens nerves, which parameter does a nurse check to determine their function?

• A. Tongue symmetry
• B. Eye movements
• C. Facial symmetry
• D. Corneal reflex

Correct answer: B

Rationale: The correct answer is B: Eye movements. When assessing the oculomotor, trochlear, and abducens nerves, evaluating eye movements is crucial. This assessment includes checking the pupils for size, regularity, equality, light reactions, accommodation, and extraocular movements in various gaze positions. Tongue symmetry is primarily used to evaluate cranial nerve XII (hypoglossal nerve) function. Facial symmetry is a key indicator of cranial nerve VII (facial nerve) function. The corneal reflex assesses sensory afferents in cranial nerve V (trigeminal nerve) and motor efferents in cranial nerve VII (facial nerve).

4. The nurse is assessing the dental status of an 18-month-old child. How many teeth should the nurse expect to examine?

• A. 6
• B. 8
• C. 12
• D. 16

Correct answer: C

Rationale: An 18-month-old child should have approximately 12 teeth. In general, children begin dentition around 6 months of age. During the first 2 years of life, a quick guide to the number of teeth a child should have is as follows: Subtract the number 6 from the number of months in the age of the child. In this example, the child is 18 months old, so the formula is 18 - 6 = 12. The correct answer is 12. Choice A (6) is incorrect as it does not consider the child's age. Choices B (8) and D (16) are incorrect as they do not align with the dental development timeline and the specific age of the child in question.

5. A paraplegic client is in the hospital to be treated for an electrolyte imbalance. Which level of care is the client currently receiving?

• A. primary prevention
• B. secondary prevention
• C. tertiary prevention
• D. health promotion

Correct answer: B

Rationale: The correct answer is B: secondary prevention. The client is currently receiving secondary prevention care. Secondary prevention focuses on early detection of disease, prompt intervention, and health maintenance for clients experiencing health problems. In this case, the electrolyte imbalance is a health problem that requires treatment to prevent further complications. Choices A, C, and D are incorrect because primary prevention is focused on health promotion and specific protections against illness before it occurs, tertiary prevention is aimed at helping rehabilitate clients after the illness is diagnosed and treated, and health promotion is a broader concept that includes activities aimed at improving overall health and well-being rather than targeting a specific health problem like an electrolyte imbalance.
