Nokea
The client has an order for 0.45 mg of Diltiazem. The medication vial has a concentration of 3 mg/mL. How many mL of the drug should be administered?
- A. 0.15 mL
- B. 6.6 mL
- C. 1.5 mL
- D. 0.65 Ml
Correct Answer: A
Rationale: To calculate the amount of drug to be administered, divide the ordered dose by the concentration of the medication in the vial. In this case, 0.45 mg ÷ 3 mg/mL = 0.15 mL. Therefore, the correct answer is 0.15 mL.
Choice B (6.6 mL) is incorrect as it does not result from the correct calculation. Choice C (1.5 mL) is incorrect as it is not the result of dividing the ordered dose by the concentration. Choice D (0.65 mL) is incorrect as it is not the accurate calculation based on the provided information.

While assessing for costovertebral angle tenderness, a nurse percusses the area, and the client complains of sharp pain. The nurse interprets this finding as most indicative of which disorder?
- A. Liver enlargement
- B. Ovarian infection
- C. Spleen enlargement
- D. Kidney inflammation
Correct Answer: D
Rationale: When assessing for costovertebral angle tenderness, sharp pain on percussion of the area indicates inflammation of the kidney or paranephric area. The correct technique involves placing one hand over the 12th rib, at the costovertebral angle, and thumping that hand with the ulnar edge of the other fist. The client normally feels a thud and should not experience pain. Ovarian infection, liver enlargement, or spleen enlargement are not associated with the costovertebral angle tenderness. Therefore, the correct answer is kidney inflammation.
An allergic reaction is classified as what type of pharmacological effect?
- A. a therapeutic effect
- B. a side effect
- C. an adverse effect
- D. an incompatibility
Correct Answer: C
Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.
When examining the abdomen, a nurse auscultates before palpating and percussing the abdomen. The nurse performs the assessment in this manner for which reason?
- A. It is less painful for the client.
- B. Palpation and percussion can increase peristalsis.
- C. It identifies any potential areas of abdominal tenderness.
- D. It gives the client more time to become comfortable with the examiner.
Correct Answer: B
Rationale: When performing an abdominal assessment, the nurse auscultates the abdomen after inspection. Auscultation is done before palpation and percussion because these assessment techniques can increase peristalsis, which would yield a false interpretation of bowel sounds. This sequence helps prevent false interpretations of bowel sounds due to increased peristalsis caused by palpation and percussion. Options A, C, and D provide incorrect reasons for auscultating the abdomen before palpating and percussing it.
The LPN is admitting a client to the unit, and the client has rapidly blinking eyes, a stuck-out tongue, and a distorted posture. Which of these medications is the client most likely taking?
- A. Clozapine
- B. Fluoxetine
- C. Ondansetron
- D. Haloperidol
Correct Answer: D
Rationale: The correct answer is Haloperidol. Haloperidol is a first-generation antipsychotic that blocks dopamine receptors and is most likely to cause extrapyramidal symptoms (EPS), such as tardive dyskinesia. Symptoms of tardive dyskinesia include rapid blinking, mouth movements, sticking out the tongue, rapid body movements, and a distorted posture. Haloperidol is associated with a higher risk of EPS compared to other antipsychotic medications like Clozapine. Clozapine is known for having a lower risk of causing EPS. Fluoxetine is a selective serotonin reuptake inhibitor used for depression and anxiety, not typically associated with these movement disorder symptoms. Ondansetron is an antiemetic used to prevent nausea and vomiting, not linked to these extrapyramidal symptoms.
A nurse sees documentation in the client's record indicating that the health care provider has noted the presence of adventitious breath sounds. The nurse knows that these types of sounds have which aspect?
- A. Normally heard in the lungs
- B. Hollow sounds heard over the trachea and larynx
- C. Rustling sounds heard over the peripheral lung fields
- D. Abnormal sounds that should not be heard in the lungs
Correct Answer: D
Rationale: Adventitious breath sounds are abnormal sounds that are not normally heard in the lungs. These sounds are added sounds superimposed on the breath sounds. They are caused by air colliding with secretions in the tracheobronchial passageways or when previously deflated airways pop open. Hollow sounds heard over the trachea and larynx are normal bronchial (tracheal) breath sounds, not adventitious. Rustling sounds heard over the peripheral lung fields are normal vesicular breath sounds, not adventitious. Therefore, the correct answer is that adventitious breath sounds are abnormal sounds that should not be heard in the lungs.
