Correct Answer: D

Rationale: Albuterol via jet nebulizer is the correct choice in this scenario as it is a short-acting bronchodilator that quickly relieves bronchospasm during an asthma exacerbation. Cromolyn (Choice A) is a mast cell stabilizer used for prevention, not quick relief. Budesonide (Choice B) is an inhaled corticosteroid used for long-term control, not for acute symptom relief. Montelukast (Choice C) is a leukotriene receptor antagonist used for maintenance therapy, not for immediate symptom relief during an exacerbation.

Correct Answer: C

Rationale: Cheddar cheese is indeed a good source of protein, providing a significant amount per serving. While chicken and tofu are also high in protein, cheddar cheese can be a beneficial source, especially for individuals looking for non-meat options. Almonds, while nutritious, are not as high in protein compared to the other options listed.

Correct Answer: B

Rationale: The correct answer is B: 'Eliminate areas of standing water.' This is an essential primary prevention strategy for West Nile virus as it helps prevent the breeding of mosquitoes that spread the virus. Choices A, C, and D are incorrect. Avoiding exposure to deer ticks is more relevant for Lyme disease, using a respiratory mask when cleaning bird coops is not a primary prevention strategy for West Nile virus, and planning outdoor activities after dusk does not directly address the prevention of West Nile virus transmission.

Correct Answer: B

Rationale: The correct first action for the nurse to take when caring for a client with pneumonia who has a new prescription for antibiotics is to obtain a sputum culture. This is important to identify the specific bacteria causing the pneumonia before administering antibiotics. Administering the antibiotic immediately (Choice A) may not be appropriate without knowing the specific pathogen. Notifying the provider of the prescription (Choice C) is important but not the first action to be taken. Checking the client's allergy history (Choice D) is relevant but not the priority in this situation.

Correct Answer: C

Rationale: The correct angle for administering a subcutaneous injection, such as insulin, is 90 degrees. This angle allows for the medication to be delivered into the subcutaneous layer of tissue beneath the skin. A 45-degree angle is typically used for administering subcutaneous injections in infants or those with reduced adipose tissue, while a 60-degree angle is commonly used for intramuscular injections. A 30-degree angle is not a standard angle for subcutaneous injections.
