Correct Answer: A

Rationale: The client undergoing a mammogram should be instructed to omit deodorants or powders beforehand because they can interfere with the imaging results. Answer A is correct as it aligns with the preparation needed before a mammogram to ensure accurate results. Answer B is incorrect because there is no requirement for fat intake restrictions before a mammogram. Answer C is incorrect because mammography does not replace the necessity of self-breast exams; both are crucial for maintaining breast health. Answer D is incorrect because a mammogram does not require higher doses of radiation than an x-ray. In fact, mammography uses a low dose of radiation to create images for breast examination.

Correct Answer: D

Rationale: Abnormal grieving is often characterized by a lack of sadness or acknowledgment of the loss. In this scenario, the statement 'Sally has not been sad at all about Daddy's death. She acts like nothing has happened' indicates abnormal grieving as it suggests a lack of emotional response or denial of the death. On the other hand, choices A, B, and C all describe normal grieving reactions: crying episodes, selective memory of the deceased, and feelings of longing after the funeral. These responses are typical in the grieving process. Therefore, choice D is the correct answer, highlighting a potential abnormality in the grieving process.

Correct Answer: A

Rationale: When providing care to a client with a cough, it is crucial to wear a mask to protect oneself from inhaling respiratory droplets containing infectious agents. The primary mode of transmission for coughs is through airborne droplets, making a mask the most appropriate choice to prevent the spread of respiratory infections. Gloves and gowns are more relevant when there is a risk of contact with bodily fluids, which is not the main concern with a cough. Shoe covers are not necessary in this scenario as the transmission of respiratory infections is not linked to footwear. Therefore, wearing a mask is the best choice to prevent airborne transmission and ensure the safety of the healthcare provider.

Correct Answer: A

Rationale: The correct answer is 'denial and fantasy.' Denial involves blocking external events from awareness to avoid anxiety, while fantasy is escaping to a more comfortable, less threatening place. These mechanisms can protect individuals from anxiety by providing temporary relief or distraction. Choices B, C, and D are incorrect. Rationalization and suppression do not directly protect individuals from anxiety. Regression and displacement involve reverting to earlier developmental stages or redirecting emotions to a substitute target, which do not directly shield individuals from anxiety. Reaction formation and projection entail behaving in the opposite way to one's impulses or attributing one's feelings to others respectively, which do not directly protect individuals from anxiety.

Correct Answer: B

Rationale: The correct answer is 'Mania.' A client with a serum sodium level of 170 meq/L has hypernatremia, which can lead to manic behavior. Hypernatremia is associated with irritability, restlessness, confusion, and in severe cases, manic symptoms. Choices A, C, and D (Anger, Depression, Psychosis) are not typically associated with hypernatremia and are, therefore, incorrect in this context.
