1. When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, what should be instructed?

Correct answer: B

Rationale: When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, it is crucial to discontinue the medication for a few weeks. Prolonged use of decongestant drops can lead to rebound congestion, which is relieved by stopping the medication for a period of time. Nasal congestion occurs due to various factors like infection, inflammation, or allergy, leading to swelling of the nasal cavity. Nasal decongestants work by stimulating alpha-adrenergic receptors, causing vasoconstriction and shrinking of nasal mucous membranes. However, prolonged use can result in vasodilation, worsening nasal congestion. Switching to a stronger dose of the same medication is not recommended as it can exacerbate the issue. Continuing the same medication more frequently or using a combination of medications are also not advised and may lead to side effects. Educating individuals on proper decongestant use and potential risks of prolonged usage is essential, especially for those with specific health conditions.

2. The PN is caring for a client with diabetes insipidus. The nurse can expect the lab work to show:

Correct answer: D

Rationale: In diabetes insipidus, the pituitary releases too much antidiuretic hormone (ADH), causing the client to produce a large amount of dilute urine (decreased osmolarity) and leading to dehydration (elevated serum osmolarity). Therefore, the correct answer is decreased urine osmolarity and elevated serum osmolarity. Choice C, elevated urine osmolarity and decreased serum osmolarity, is incorrect for diabetes insipidus, as it is more characteristic of syndrome of inappropriate ADH (SIADH). Choices A and B, elevated urine osmolarity and elevated serum osmolarity, and decreased urine osmolarity and decreased serum osmolarity, respectively, are generally not seen in diabetes insipidus, as urine and serum osmolarity typically move in opposite directions in this condition.

3. A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?

Correct answer: A

Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.

4. Teaching about the need to avoid foods high in potassium is most important for which client?

Correct answer: D

Rationale: Clients with renal disease are predisposed to hyperkalemia and should avoid foods high in potassium. High potassium levels can further burden the kidneys and worsen the condition. Choices A, B, and C are incorrect because clients receiving diuretic therapy, with an ileostomy, or with metabolic alkalosis are at risk for hypokalemia, which is low potassium levels. Therefore, these clients should actually be encouraged to eat foods high in potassium to maintain adequate levels and prevent complications associated with hypokalemia.

5. The client is wheezing and struggling to breathe. Which of the inhaled medications is indicated at this time?

Correct answer: D

Rationale: The correct answer is Albuterol (Atrovent) because it is a rapid-acting bronchodilator, essential for a client experiencing wheezing and difficulty breathing. Albuterol acts quickly, dilating the airways and providing immediate relief in cases of respiratory distress. Fluticasone (Flovent) and Salmeterol (Serevent) are maintenance medications for long-term asthma control, not suitable for acute situations described. Theophylline (Theodur) is a bronchodilator but with a slower onset compared to Albuterol, making it less appropriate for a client in immediate distress.
