Health Promotion and Maintenance NCLEX PN Questions - Nurselytic

Correct Answer: D

Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.

Correct Answer: C

Rationale: The correct answer is 'certain diet and foods.' Risk factors that increase the chances of getting skin cancer include having a light or fair complexion, a history of bad sunburns, personal or family history of skin cancer, outdoor activities with sun exposure, exposure to X-rays or radiation, exposure to certain chemicals, repeated trauma or injury resulting in scars, age over 50, male gender, and living in specific geographic locations. These factors can contribute to the development of skin cancer. Avoiding exposure to the sun, using protective clothing and sunscreen, and regular skin inspections are key preventive measures.
Choice C, 'certain diet and foods,' is incorrect as diet is not a primary risk factor for skin cancer. Options A, B, and D are all valid risk factors associated with an increased risk of developing skin cancer.

Correct Answer: C

Rationale:
To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint.
Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I.
Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve).
Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.

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.

Correct Answer: B

Rationale:
To calculate the correct dosage, first convert the client's weight from pounds to kilograms. As 1 kg = 2.2 pounds, 176 pounds ÷ 2.2 = 80 kg. The client should receive 0.2 units for every kilogram, which equals 16 units.
Therefore, the total amount to prepare is 16 units x 100 units/mL = 1600 units. Considering the medication concentration of 100 units/mL, 1600 units ÷ 100 units/mL = 16 mL. However, since the question asks for the number of units, the final answer is 16 units x 2 injections = 32 units.
Therefore, the LPN should prepare 32 units for administration.
