Nursing Elites

1. The LPN is caring for a 9-month-old infant. Which of these behaviors exhibited by the child warrants further investigation?

• A. She prefers crawling over walking and makes no attempt to walk.
• B. She seems distressed by new adults.
• C. She does not respond to her own name.
• D. She only babbles "mama"? and "dada."?

Correct answer: C

Rationale: The correct answer is that the child does not respond to her own name. By 9 months, children should be babbling simple words, crawling, and responding to their name. Not responding to one's name can be an early indicator of a potential developmental delay, warranting further investigation. Preferring crawling over walking, being distressed by new adults, and babbling 'mama' and 'dada' are typical behaviors for a 9-month-old and do not necessarily require immediate concern.

2. What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?

• A. Dextrose concentrations below 20% can be safely administered through a peripheral IV; dextrose concentrations above 20% should not be administered through a peripheral IV.
• B. Dextrose concentrations below 5% can be safely administered through a peripheral IV; dextrose concentrations above 5% should not be administered through a peripheral IV.
• C. Dextrose concentrations below 10% can be safely administered through a peripheral IV; dextrose concentrations above 10% should not be administered through a peripheral IV.
• D. Dextrose concentrations above 5% can be safely administered through a peripheral IV; dextrose concentrations below 5% should not be administered through a peripheral IV.

Correct answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.

3. A nurse assisting with data collection notes that the client exhibits rapid, involuntary oscillating movements of the eyeball when looking at the nurse. The nurse documents this finding using which term?

• A. Ptosis
• B. Nystagmus
• C. Scleral icterus
• D. Exophthalmos

Correct answer: B

Rationale: When a nurse observes rapid, involuntary oscillating movements of the eyeball in a client, this is described as nystagmus. Nystagmus appears as a fine oscillating movement, most notable around the iris. It is important to assess for nystagmus when evaluating ocular muscle weakness. Mild nystagmus at extreme lateral gaze is considered normal; nystagmus in any other position is not. Ptosis refers to a drooping of the eyelid, not rapid eye movements. Scleral icterus is the yellowing of the sclera up to the cornea, indicating jaundice, not related to eye movements. Exophthalmos is a noticeable protrusion of the eyeball, typically seen in hyperthyroidism, not associated with rapid oscillating eye movements.

4. 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).

5. When reviewing a client's medical notes to confirm pregnancy, a nurse should look for which finding to determine that pregnancy is confirmed?

• A. Amenorrhea
• B. Thinning of the cervix
• C. Palpable fetal movement
• D. Positive result on a home urine test for pregnancy

Correct answer: C

Rationale: To confirm pregnancy, the presence of palpable fetal movement is a positive indicator. Palpable fetal movement is a certain sign of pregnancy, known as a fetal movement felt by the examiner. Amenorrhea is a presumptive sign of pregnancy as it is reported by the woman but is not confirmatory. Thinning of the cervix (Hegar sign) is a probable sign of pregnancy, which is not confirmatory. A positive result on a home urine test for pregnancy is also a probable indicator. However, a positive pregnancy test result can sometimes yield false-positive results due to various factors like medication, recent pregnancy, or errors in reading.
